Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513110, here are decompositions:

19 + 31513091 = 31513110
37 + 31513073 = 31513110
47 + 31513063 = 31513110
53 + 31513057 = 31513110
61 + 31513049 = 31513110
73 + 31513037 = 31513110
103 + 31513007 = 31513110
107 + 31513003 = 31513110

Showing the first eight; more decompositions exist.
