Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510246, here are decompositions:

3 + 31510243 = 31510246
23 + 31510223 = 31510246
29 + 31510217 = 31510246
59 + 31510187 = 31510246
107 + 31510139 = 31510246
113 + 31510133 = 31510246
167 + 31510079 = 31510246
239 + 31510007 = 31510246

Showing the first eight; more decompositions exist.
