Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510026, here are decompositions:

5 + 31510021 = 31510026
17 + 31510009 = 31510026
19 + 31510007 = 31510026
59 + 31509967 = 31510026
113 + 31509913 = 31510026
137 + 31509889 = 31510026
263 + 31509763 = 31510026
269 + 31509757 = 31510026

Showing the first eight; more decompositions exist.
