You have not proved a thing; you merely launched a new hypothesis.

You are not proving anywhere that, for a fixed factorial, it exists a twin prime that
added to the factorial will always give another twin pair. You only give some evidence.
Indeed, a very very little evidence for it. Moreover, you don't need to prove that the sum
is a twin, if you can simply prove that it exists a twin for every factorial, then you
would have proven the TP conjecture! But you can't prove it with your idea, unless you
build a chain of numbers that are always twins (you have to prove it) and you prove that
adding that twins to factorials give new twins. That's it, to make explicit the twins that

Nevertheless, your idea about that relation between two twin primes seems beautiful to me.
Will all the twin primes be related to a factorial and another twin prime? If it is true,
is it trivial? If it is not trivial, is there a simple formula to regulate this fact? How
many primes will you add to the same factorial before you change to the next factorial?
Because factorials grow a lot faster than twin primes do (at least I think so)

Or will it be a consecuence of the small law of numbers? Can you go further with your
checking? Go up with the twins to, say, 10^8, if you can, and then return with the results
if you think they are relevant.

Subject: [PrimeNumbers] Infinite Number of Twin Primes

Here is a demonstration that there are an infinite number of Twin Primes,
and a method of finding them.

Consider the following twin primes:

(5,7)
(11,13) (17, 19)
(29,31) (41,43)
(149,151) (179,181) ...

Now put the appropriate factorial ahead of them

(2!+3,2!+5)
(3!+5,3!+7) (3!+11,3!+13) note (3!+17,3!+19=25) does not woork
(4!+5,4!+7) (4!+17,4!+19)
(5!+29,5!+31) (5!+59,5!+61)

This is the pattern: Start at the next factorial and add prior pairs of twin primes,
until you obtain a pair of twin primes for that factorial.

The equivalent theorem is "There is always a pair of twin primes between a factorial
and its successor factorial."

Then Ininite Twin Primes are proved since 2!, 3!, ..., n!, ... are infinite in number.

The familiar formula:

n!+2, n!+3, ..., n!+n

shows that these numbers are all composite,
but for this value of n we start testing the previous twin primes at

n!+(n+1) and (n-1)! > n+1 for n>4. This is easily proved by induction on n:

(n-1)! > n+1
n! = n(n-1)! > n^2+n > n+2 since

n^2 > 2.

I found that

allowing the primes generated by the n factorial to go "backwards" to be checked with
former factorials.

But then I got stuck. No twin primes with (881,883) with n! from 3 to 7.

PS Milton still has an escape, if he has a way to determine a twin that added with the
factorial will give another twin... but this is silly, cause that method would prove TP
conjecture itself!

The answer is, he doesn't, because it won't work. This one didn't even need a
computer search; it fell to a search by hand. I would appreciate a third

Start from (3,5).

2!+3, 2!+5 adds (5,7). Values found until now: (3,5), (5,7).

Values found until now: (3,5), (5,7), (11,13), (17,19).

Values found until now: (3,5), (5,7), (11,13), (17,19), (29,31), (41,43).

(269,271).
Values found until now: (3,5), (5,7), (11,13), (17,19), (29,31), (41,43),
(137,139), (149,151), (269,271).

Values found until now: (3,5), (5,7), (11,13), (17,19), (29,31), (41,43),
(137,139), (149,151), (269,271), (857,859).

Finally, 7! doesn't produce any values. And thus Milton's conjecture is
demolished, as about anything that he brainfarts on this list.
