Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510068, here are decompositions:

47 + 31510021 = 31510068
59 + 31510009 = 31510068
61 + 31510007 = 31510068
67 + 31510001 = 31510068
97 + 31509971 = 31510068
101 + 31509967 = 31510068
127 + 31509941 = 31510068
179 + 31509889 = 31510068

Showing the first eight; more decompositions exist.
