      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?
      I will apreciate yor answer.
      Bye

      ... 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

        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.
