Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510126, here are decompositions:

5 + 31510121 = 31510126
47 + 31510079 = 31510126
233 + 31509893 = 31510126
353 + 31509773 = 31510126
443 + 31509683 = 31510126
467 + 31509659 = 31510126
509 + 31509617 = 31510126
569 + 31509557 = 31510126

Showing the first eight; more decompositions exist.
