Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617468, here are decompositions:

7 + 31617461 = 31617468
11 + 31617457 = 31617468
19 + 31617449 = 31617468
37 + 31617431 = 31617468
59 + 31617409 = 31617468
61 + 31617407 = 31617468
89 + 31617379 = 31617468
97 + 31617371 = 31617468

Showing the first eight; more decompositions exist.
