Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493226, here are decompositions:

73 + 31493153 = 31493226
157 + 31493069 = 31493226
173 + 31493053 = 31493226
179 + 31493047 = 31493226
197 + 31493029 = 31493226
229 + 31492997 = 31493226
263 + 31492963 = 31493226
283 + 31492943 = 31493226

Showing the first eight; more decompositions exist.
