Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549796, here are decompositions:

43 + 31549753 = 31549796
67 + 31549729 = 31549796
79 + 31549717 = 31549796
199 + 31549597 = 31549796
457 + 31549339 = 31549796
613 + 31549183 = 31549796
709 + 31549087 = 31549796
757 + 31549039 = 31549796

Showing the first eight; more decompositions exist.
