Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614512, here are decompositions:

19 + 31614493 = 31614512
229 + 31614283 = 31614512
283 + 31614229 = 31614512
313 + 31614199 = 31614512
331 + 31614181 = 31614512
379 + 31614133 = 31614512
421 + 31614091 = 31614512
673 + 31613839 = 31614512

Showing the first eight; more decompositions exist.
