Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627104, here are decompositions:

13 + 31627091 = 31627104
31 + 31627073 = 31627104
53 + 31627051 = 31627104
71 + 31627033 = 31627104
97 + 31627007 = 31627104
127 + 31626977 = 31627104
137 + 31626967 = 31627104
211 + 31626893 = 31627104

Showing the first eight; more decompositions exist.
