Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510634, here are decompositions:

3 + 31510631 = 31510634
7 + 31510627 = 31510634
31 + 31510603 = 31510634
61 + 31510573 = 31510634
73 + 31510561 = 31510634
271 + 31510363 = 31510634
313 + 31510321 = 31510634
523 + 31510111 = 31510634

Showing the first eight; more decompositions exist.
