Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549596, here are decompositions:

5 + 31549591 = 31549596
7 + 31549589 = 31549596
17 + 31549579 = 31549596
97 + 31549499 = 31549596
157 + 31549439 = 31549596
193 + 31549403 = 31549596
223 + 31549373 = 31549596
257 + 31549339 = 31549596

Showing the first eight; more decompositions exist.
