Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550596, here are decompositions:

3 + 31550593 = 31550596
23 + 31550573 = 31550596
53 + 31550543 = 31550596
59 + 31550537 = 31550596
137 + 31550459 = 31550596
149 + 31550447 = 31550596
239 + 31550357 = 31550596
257 + 31550339 = 31550596

Showing the first eight; more decompositions exist.
