Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508064, here are decompositions:

37 + 31508027 = 31508064
47 + 31508017 = 31508064
61 + 31508003 = 31508064
73 + 31507991 = 31508064
83 + 31507981 = 31508064
113 + 31507951 = 31508064
151 + 31507913 = 31508064
163 + 31507901 = 31508064

Showing the first eight; more decompositions exist.
