Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617466, here are decompositions:

5 + 31617461 = 31617466
17 + 31617449 = 31617466
53 + 31617413 = 31617466
59 + 31617407 = 31617466
137 + 31617329 = 31617466
173 + 31617293 = 31617466
197 + 31617269 = 31617466
227 + 31617239 = 31617466

Showing the first eight; more decompositions exist.
