Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618110, here are decompositions:

11 + 31618099 = 31618110
47 + 31618063 = 31618110
53 + 31618057 = 31618110
61 + 31618049 = 31618110
67 + 31618043 = 31618110
107 + 31618003 = 31618110
109 + 31618001 = 31618110
113 + 31617997 = 31618110

Showing the first eight; more decompositions exist.
