Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617262, here are decompositions:

11 + 31617251 = 31617262
23 + 31617239 = 31617262
113 + 31617149 = 31617262
233 + 31617029 = 31617262
239 + 31617023 = 31617262
251 + 31617011 = 31617262
263 + 31616999 = 31617262
311 + 31616951 = 31617262

Showing the first eight; more decompositions exist.
