Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614646, here are decompositions:

3 + 31614643 = 31614646
5 + 31614641 = 31614646
59 + 31614587 = 31614646
83 + 31614563 = 31614646
197 + 31614449 = 31614646
269 + 31614377 = 31614646
293 + 31614353 = 31614646
419 + 31614227 = 31614646

Showing the first eight; more decompositions exist.
