Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510032, here are decompositions:

11 + 31510021 = 31510032
23 + 31510009 = 31510032
31 + 31510001 = 31510032
41 + 31509991 = 31510032
61 + 31509971 = 31510032
83 + 31509949 = 31510032
139 + 31509893 = 31510032
149 + 31509883 = 31510032

Showing the first eight; more decompositions exist.
