Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516092, here are decompositions:

5 + 31516087 = 31516092
11 + 31516081 = 31516092
31 + 31516061 = 31516092
71 + 31516021 = 31516092
103 + 31515989 = 31516092
151 + 31515941 = 31516092
173 + 31515919 = 31516092
193 + 31515899 = 31516092

Showing the first eight; more decompositions exist.
