Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617724, here are decompositions:

11 + 31617713 = 31617724
137 + 31617587 = 31617724
191 + 31617533 = 31617724
227 + 31617497 = 31617724
263 + 31617461 = 31617724
293 + 31617431 = 31617724
311 + 31617413 = 31617724
317 + 31617407 = 31617724

Showing the first eight; more decompositions exist.
