Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615110, here are decompositions:

13 + 31615097 = 31615110
47 + 31615063 = 31615110
71 + 31615039 = 31615110
97 + 31615013 = 31615110
103 + 31615007 = 31615110
157 + 31614953 = 31615110
167 + 31614943 = 31615110
181 + 31614929 = 31615110

Showing the first eight; more decompositions exist.
