Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493224, here are decompositions:

23 + 31493201 = 31493224
53 + 31493171 = 31493224
71 + 31493153 = 31493224
167 + 31493057 = 31493224
227 + 31492997 = 31493224
233 + 31492991 = 31493224
281 + 31492943 = 31493224
317 + 31492907 = 31493224

Showing the first eight; more decompositions exist.
