Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597064, here are decompositions:

13 + 31597051 = 31597064
61 + 31597003 = 31597064
67 + 31596997 = 31597064
73 + 31596991 = 31597064
151 + 31596913 = 31597064
157 + 31596907 = 31597064
181 + 31596883 = 31597064
271 + 31596793 = 31597064

Showing the first eight; more decompositions exist.
