Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493296, here are decompositions:

5 + 31493291 = 31493296
47 + 31493249 = 31493296
227 + 31493069 = 31493296
239 + 31493057 = 31493296
257 + 31493039 = 31493296
353 + 31492943 = 31493296
389 + 31492907 = 31493296
449 + 31492847 = 31493296

Showing the first eight; more decompositions exist.
