Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492312, here are decompositions:

53 + 31492259 = 31492312
149 + 31492163 = 31492312
233 + 31492079 = 31492312
239 + 31492073 = 31492312
251 + 31492061 = 31492312
281 + 31492031 = 31492312
353 + 31491959 = 31492312
419 + 31491893 = 31492312

Showing the first eight; more decompositions exist.
