Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614770, here are decompositions:

37 + 31614733 = 31614770
67 + 31614703 = 31614770
73 + 31614697 = 31614770
127 + 31614643 = 31614770
139 + 31614631 = 31614770
211 + 31614559 = 31614770
223 + 31614547 = 31614770
277 + 31614493 = 31614770

Showing the first eight; more decompositions exist.
