Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513164, here are decompositions:

17 + 31513147 = 31513164
41 + 31513123 = 31513164
47 + 31513117 = 31513164
73 + 31513091 = 31513164
101 + 31513063 = 31513164
107 + 31513057 = 31513164
127 + 31513037 = 31513164
131 + 31513033 = 31513164

Showing the first eight; more decompositions exist.
