Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645146, here are decompositions:

5 + 8645141 = 8645146
23 + 8645123 = 8645146
137 + 8645009 = 8645146
197 + 8644949 = 8645146
227 + 8644919 = 8645146
233 + 8644913 = 8645146
347 + 8644799 = 8645146
443 + 8644703 = 8645146

Showing the first eight; more decompositions exist.
