Hello:
Mi name is Juan Volpe and I like prime numbers too.
I´ve studied prime numers and I foud that every pair of primes only
2 apart are like 6n +-1 e.g. (5,7), (11,13), (17,19).
It's this one unsolved problem to?

No, this is easy. If the two numbers weren't 6n+/-1 then one of the
numbers would be 6n+3. But if it is 6n+3 then it is divisible by 3. So if
n=0 then you have the prime 3 (and the pair 3,5), but for n>1 6n+3 has 3 as
a factor, so isn't prime.
