Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614940, here are decompositions:

11 + 31614929 = 31614940
41 + 31614899 = 31614940
59 + 31614881 = 31614940
89 + 31614851 = 31614940
101 + 31614839 = 31614940
107 + 31614833 = 31614940
233 + 31614707 = 31614940
239 + 31614701 = 31614940

Showing the first eight; more decompositions exist.
