Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513064, here are decompositions:

7 + 31513057 = 31513064
31 + 31513033 = 31513064
61 + 31513003 = 31513064
67 + 31512997 = 31513064
73 + 31512991 = 31513064
151 + 31512913 = 31513064
157 + 31512907 = 31513064
223 + 31512841 = 31513064

Showing the first eight; more decompositions exist.
