Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510182, here are decompositions:

13 + 31510169 = 31510182
43 + 31510139 = 31510182
61 + 31510121 = 31510182
71 + 31510111 = 31510182
89 + 31510093 = 31510182
103 + 31510079 = 31510182
173 + 31510009 = 31510182
181 + 31510001 = 31510182

Showing the first eight; more decompositions exist.
