Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617510, here are decompositions:

7 + 31617503 = 31617510
13 + 31617497 = 31617510
17 + 31617493 = 31617510
53 + 31617457 = 31617510
61 + 31617449 = 31617510
79 + 31617431 = 31617510
97 + 31617413 = 31617510
101 + 31617409 = 31617510

Showing the first eight; more decompositions exist.
