Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617560, here are decompositions:

31 + 31617529 = 31617560
67 + 31617493 = 31617560
103 + 31617457 = 31617560
151 + 31617409 = 31617560
157 + 31617403 = 31617560
181 + 31617379 = 31617560
199 + 31617361 = 31617560
277 + 31617283 = 31617560

Showing the first eight; more decompositions exist.
