Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614984, here are decompositions:

31 + 31614953 = 31614984
41 + 31614943 = 31614984
43 + 31614941 = 31614984
103 + 31614881 = 31614984
131 + 31614853 = 31614984
151 + 31614833 = 31614984
197 + 31614787 = 31614984
251 + 31614733 = 31614984

Showing the first eight; more decompositions exist.
