Is well known that prime numbers can be found with sieve of Eratosthenes
and that they are all type 6n+1 or 6n-1.

I do not think that it's already known that prime number are all 6n +-1
type numbers excluded those which are the product of two members of the
groupincluded each number with itself.

. Once you find an exception (eg 25 or 35 == 5 * 5 5 * 7) you can proceed in
escluding numbers with a new sieve
by adding to the excluded number 6* both_generating_factors
(i.e. starting from 35, 30 and 42 should be added as sieve indexes which
generates two escluding line which are (65 95 125 ...) and (77 139 181 ....)
that caused it

I do not know if this discovery is interesting but I'm working on a C
program to verify what is fast find prime numbers with this method.

2 isn't. There's another one too, but I'll let you work that one out yourself.

You think incorrectly. It's a direct consequence of the corrected version of your first sentence.
