Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510092, here are decompositions:

13 + 31510079 = 31510092
71 + 31510021 = 31510092
83 + 31510009 = 31510092
101 + 31509991 = 31510092
151 + 31509941 = 31510092
179 + 31509913 = 31510092
199 + 31509893 = 31510092
241 + 31509851 = 31510092

Showing the first eight; more decompositions exist.
