Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645270, here are decompositions:

3 + 8645267 = 8645270
13 + 8645257 = 8645270
31 + 8645239 = 8645270
157 + 8645113 = 8645270
199 + 8645071 = 8645270
223 + 8645047 = 8645270
241 + 8645029 = 8645270
307 + 8644963 = 8645270

Showing the first eight; more decompositions exist.
