Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614812, here are decompositions:

43 + 31614769 = 31614812
79 + 31614733 = 31614812
109 + 31614703 = 31614812
181 + 31614631 = 31614812
211 + 31614601 = 31614812
601 + 31614211 = 31614812
613 + 31614199 = 31614812
631 + 31614181 = 31614812

Showing the first eight; more decompositions exist.
