Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617256, here are decompositions:

3 + 31617253 = 31617256
5 + 31617251 = 31617256
17 + 31617239 = 31617256
89 + 31617167 = 31617256
107 + 31617149 = 31617256
179 + 31617077 = 31617256
227 + 31617029 = 31617256
233 + 31617023 = 31617256

Showing the first eight; more decompositions exist.
