Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549294, here are decompositions:

17 + 31549277 = 31549294
53 + 31549241 = 31549294
113 + 31549181 = 31549294
251 + 31549043 = 31549294
311 + 31548983 = 31549294
617 + 31548677 = 31549294
641 + 31548653 = 31549294
653 + 31548641 = 31549294

Showing the first eight; more decompositions exist.
