Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512226, here are decompositions:

17 + 31512209 = 31512226
107 + 31512119 = 31512226
113 + 31512113 = 31512226
167 + 31512059 = 31512226
233 + 31511993 = 31512226
257 + 31511969 = 31512226
293 + 31511933 = 31512226
353 + 31511873 = 31512226

Showing the first eight; more decompositions exist.
