Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510794, here are decompositions:

5 + 31510789 = 31510794
13 + 31510781 = 31510794
23 + 31510771 = 31510794
31 + 31510763 = 31510794
37 + 31510757 = 31510794
41 + 31510753 = 31510794
103 + 31510691 = 31510794
113 + 31510681 = 31510794

Showing the first eight; more decompositions exist.
