Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617506, here are decompositions:

3 + 31617503 = 31617506
13 + 31617493 = 31617506
97 + 31617409 = 31617506
103 + 31617403 = 31617506
127 + 31617379 = 31617506
223 + 31617283 = 31617506
307 + 31617199 = 31617506
373 + 31617133 = 31617506

Showing the first eight; more decompositions exist.
