Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511334, here are decompositions:

7 + 31511327 = 31511334
13 + 31511321 = 31511334
47 + 31511287 = 31511334
53 + 31511281 = 31511334
73 + 31511261 = 31511334
103 + 31511231 = 31511334
163 + 31511171 = 31511334
167 + 31511167 = 31511334

Showing the first eight; more decompositions exist.
