Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510596, here are decompositions:

23 + 31510573 = 31510596
43 + 31510553 = 31510596
79 + 31510517 = 31510596
107 + 31510489 = 31510596
109 + 31510487 = 31510596
137 + 31510459 = 31510596
149 + 31510447 = 31510596
163 + 31510433 = 31510596

Showing the first eight; more decompositions exist.
