Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513176, here are decompositions:

29 + 31513147 = 31513176
53 + 31513123 = 31513176
59 + 31513117 = 31513176
103 + 31513073 = 31513176
113 + 31513063 = 31513176
127 + 31513049 = 31513176
139 + 31513037 = 31513176
173 + 31513003 = 31513176

Showing the first eight; more decompositions exist.
