Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550514, here are decompositions:

5 + 31550509 = 31550514
43 + 31550471 = 31550514
53 + 31550461 = 31550514
67 + 31550447 = 31550514
113 + 31550401 = 31550514
157 + 31550357 = 31550514
227 + 31550287 = 31550514
257 + 31550257 = 31550514

Showing the first eight; more decompositions exist.
