Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626186, here are decompositions:

19 + 31626167 = 31626186
107 + 31626079 = 31626186
113 + 31626073 = 31626186
167 + 31626019 = 31626186
199 + 31625987 = 31626186
223 + 31625963 = 31626186
233 + 31625953 = 31626186
269 + 31625917 = 31626186

Showing the first eight; more decompositions exist.
