Well, to begin with, 2 and 3 are not twin primes. The first twin primes are 3 and 5, but then 5 and 7 are also twin primes. After that, it's 11 and 13, then 17 and 19, 29 and 31, and 41 and 43. Twin primes are distinguished by having a difference of 2 between them.
They are called twin primes. 3 & 5 are twin primes.
