Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510936, here are decompositions:

3 + 31510933 = 31510936
5 + 31510931 = 31510936
89 + 31510847 = 31510936
137 + 31510799 = 31510936
167 + 31510769 = 31510936
173 + 31510763 = 31510936
179 + 31510757 = 31510936
257 + 31510679 = 31510936

Showing the first eight; more decompositions exist.
