Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617516, here are decompositions:

13 + 31617503 = 31617516
19 + 31617497 = 31617516
23 + 31617493 = 31617516
59 + 31617457 = 31617516
67 + 31617449 = 31617516
103 + 31617413 = 31617516
107 + 31617409 = 31617516
109 + 31617407 = 31617516

Showing the first eight; more decompositions exist.
