Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513134, here are decompositions:

11 + 31513123 = 31513134
17 + 31513117 = 31513134
43 + 31513091 = 31513134
61 + 31513073 = 31513134
71 + 31513063 = 31513134
97 + 31513037 = 31513134
101 + 31513033 = 31513134
127 + 31513007 = 31513134

Showing the first eight; more decompositions exist.
