Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614618, here are decompositions:

17 + 31614601 = 31614618
31 + 31614587 = 31614618
59 + 31614559 = 31614618
67 + 31614551 = 31614618
71 + 31614547 = 31614618
241 + 31614377 = 31614618
389 + 31614229 = 31614618
401 + 31614217 = 31614618

Showing the first eight; more decompositions exist.
