Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510662, here are decompositions:

5 + 31510657 = 31510662
31 + 31510631 = 31510662
59 + 31510603 = 31510662
89 + 31510573 = 31510662
101 + 31510561 = 31510662
109 + 31510553 = 31510662
173 + 31510489 = 31510662
229 + 31510433 = 31510662

Showing the first eight; more decompositions exist.
