Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626116, here are decompositions:

7 + 31626109 = 31626116
37 + 31626079 = 31626116
43 + 31626073 = 31626116
97 + 31626019 = 31626116
163 + 31625953 = 31626116
199 + 31625917 = 31626116
337 + 31625779 = 31626116
349 + 31625767 = 31626116

Showing the first eight; more decompositions exist.
