Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614590, here are decompositions:

3 + 31614587 = 31614590
31 + 31614559 = 31614590
43 + 31614547 = 31614590
67 + 31614523 = 31614590
97 + 31614493 = 31614590
307 + 31614283 = 31614590
313 + 31614277 = 31614590
373 + 31614217 = 31614590

Showing the first eight; more decompositions exist.
