Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502064, here are decompositions:

107 + 31501957 = 31502064
127 + 31501937 = 31502064
151 + 31501913 = 31502064
157 + 31501907 = 31502064
233 + 31501831 = 31502064
241 + 31501823 = 31502064
257 + 31501807 = 31502064
283 + 31501781 = 31502064

Showing the first eight; more decompositions exist.
