Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513764, here are decompositions:

43 + 31513721 = 31513764
67 + 31513697 = 31513764
71 + 31513693 = 31513764
97 + 31513667 = 31513764
103 + 31513661 = 31513764
151 + 31513613 = 31513764
157 + 31513607 = 31513764
353 + 31513411 = 31513764

Showing the first eight; more decompositions exist.
