Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617658, here are decompositions:

29 + 31617629 = 31617658
71 + 31617587 = 31617658
197 + 31617461 = 31617658
227 + 31617431 = 31617658
251 + 31617407 = 31617658
389 + 31617269 = 31617658
419 + 31617239 = 31617658
491 + 31617167 = 31617658

Showing the first eight; more decompositions exist.
