Twin primes are pairs of primes that are immediately next to each other (difference of two). The lesser of twin primes are 3, 5, 11, 17, 29, ... ( ref. ). The greater of twin primes are 5, 7, 13, 19, 31, ... ( ref. ). Therefore, the first five twin primes are [3,5] [5,7] [11,13] [17,19] [29,31].

For a given index range n, return the twin primes corresponding to that range as a two-row column array.
