Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510062, here are decompositions:

41 + 31510021 = 31510062
53 + 31510009 = 31510062
61 + 31510001 = 31510062
71 + 31509991 = 31510062
113 + 31509949 = 31510062
149 + 31509913 = 31510062
173 + 31509889 = 31510062
179 + 31509883 = 31510062

Showing the first eight; more decompositions exist.
