Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510762, here are decompositions:

5 + 31510757 = 31510762
71 + 31510691 = 31510762
83 + 31510679 = 31510762
131 + 31510631 = 31510762
359 + 31510403 = 31510762
443 + 31510319 = 31510762
593 + 31510169 = 31510762
641 + 31510121 = 31510762

Showing the first eight; more decompositions exist.
