Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627214, here are decompositions:

13 + 31627201 = 31627214
163 + 31627051 = 31627214
181 + 31627033 = 31627214
271 + 31626943 = 31627214
331 + 31626883 = 31627214
373 + 31626841 = 31627214
523 + 31626691 = 31627214
547 + 31626667 = 31627214

Showing the first eight; more decompositions exist.
