Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626214, here are decompositions:

5 + 31626209 = 31626214
17 + 31626197 = 31626214
23 + 31626191 = 31626214
47 + 31626167 = 31626214
83 + 31626131 = 31626214
173 + 31626041 = 31626214
227 + 31625987 = 31626214
233 + 31625981 = 31626214

Showing the first eight; more decompositions exist.
