Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492214, here are decompositions:

163 + 31492051 = 31492214
181 + 31492033 = 31492214
373 + 31491841 = 31492214
421 + 31491793 = 31492214
487 + 31491727 = 31492214
577 + 31491637 = 31492214
601 + 31491613 = 31492214
643 + 31491571 = 31492214

Showing the first eight; more decompositions exist.
