Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617508, here are decompositions:

5 + 31617503 = 31617508
11 + 31617497 = 31617508
47 + 31617461 = 31617508
59 + 31617449 = 31617508
101 + 31617407 = 31617508
137 + 31617371 = 31617508
179 + 31617329 = 31617508
227 + 31617281 = 31617508

Showing the first eight; more decompositions exist.
