Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510896, here are decompositions:

5 + 31510891 = 31510896
83 + 31510813 = 31510896
97 + 31510799 = 31510896
107 + 31510789 = 31510896
127 + 31510769 = 31510896
139 + 31510757 = 31510896
239 + 31510657 = 31510896
269 + 31510627 = 31510896

Showing the first eight; more decompositions exist.
