Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614442, here are decompositions:

71 + 31614371 = 31614442
89 + 31614353 = 31614442
263 + 31614179 = 31614442
269 + 31614173 = 31614442
281 + 31614161 = 31614442
479 + 31613963 = 31614442
599 + 31613843 = 31614442
641 + 31613801 = 31614442

Showing the first eight; more decompositions exist.
