Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617498, here are decompositions:

5 + 31617493 = 31617498
37 + 31617461 = 31617498
41 + 31617457 = 31617498
67 + 31617431 = 31617498
89 + 31617409 = 31617498
127 + 31617371 = 31617498
137 + 31617361 = 31617498
229 + 31617269 = 31617498

Showing the first eight; more decompositions exist.
