Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614916, here are decompositions:

17 + 31614899 = 31614916
83 + 31614833 = 31614916
239 + 31614677 = 31614916
269 + 31614647 = 31614916
353 + 31614563 = 31614916
467 + 31614449 = 31614916
563 + 31614353 = 31614916
719 + 31614197 = 31614916

Showing the first eight; more decompositions exist.
