Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617512, here are decompositions:

19 + 31617493 = 31617512
103 + 31617409 = 31617512
109 + 31617403 = 31617512
139 + 31617373 = 31617512
151 + 31617361 = 31617512
229 + 31617283 = 31617512
313 + 31617199 = 31617512
331 + 31617181 = 31617512

Showing the first eight; more decompositions exist.
