Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631270, here are decompositions:

19 + 8631251 = 8631270
23 + 8631247 = 8631270
41 + 8631229 = 8631270
71 + 8631199 = 8631270
79 + 8631191 = 8631270
103 + 8631167 = 8631270
173 + 8631097 = 8631270
229 + 8631041 = 8631270

Showing the first eight; more decompositions exist.
