Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617276, here are decompositions:

7 + 31617269 = 31617276
23 + 31617253 = 31617276
37 + 31617239 = 31617276
109 + 31617167 = 31617276
127 + 31617149 = 31617276
199 + 31617077 = 31617276
227 + 31617049 = 31617276
263 + 31617013 = 31617276

Showing the first eight; more decompositions exist.
