Problem 56190. Split Even Number Into Two Primes

Given an even whole number n (> 2), return a 2-element vector of primes, p, such that p(1) + p(2) = n. The elements of p should be in increasing numerical order (that is, p(1) <= p(2)).
Fun note: technically it cannot be guaranteed that such primes exist for any n. However, although Goldbach's Conjecture has not been formally proven, it has been verified for all n well beyond any you'll face in this problem.
