Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510632, here are decompositions:

5 + 31510627 = 31510632
29 + 31510603 = 31510632
59 + 31510573 = 31510632
71 + 31510561 = 31510632
79 + 31510553 = 31510632
173 + 31510459 = 31510632
199 + 31510433 = 31510632
229 + 31510403 = 31510632

Showing the first eight; more decompositions exist.
