Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492314, here are decompositions:

37 + 31492277 = 31492314
53 + 31492261 = 31492314
71 + 31492243 = 31492314
101 + 31492213 = 31492314
151 + 31492163 = 31492314
157 + 31492157 = 31492314
223 + 31492091 = 31492314
233 + 31492081 = 31492314

Showing the first eight; more decompositions exist.
