Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549068, here are decompositions:

17 + 31549051 = 31549068
29 + 31549039 = 31549068
59 + 31549009 = 31549068
71 + 31548997 = 31549068
107 + 31548961 = 31549068
197 + 31548871 = 31549068
211 + 31548857 = 31549068
251 + 31548817 = 31549068

Showing the first eight; more decompositions exist.
