Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617410, here are decompositions:

3 + 31617407 = 31617410
7 + 31617403 = 31617410
31 + 31617379 = 31617410
37 + 31617373 = 31617410
127 + 31617283 = 31617410
157 + 31617253 = 31617410
211 + 31617199 = 31617410
229 + 31617181 = 31617410

Showing the first eight; more decompositions exist.
