Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657448, here are decompositions:

17 + 8657431 = 8657448
61 + 8657387 = 8657448
67 + 8657381 = 8657448
71 + 8657377 = 8657448
139 + 8657309 = 8657448
157 + 8657291 = 8657448
199 + 8657249 = 8657448
211 + 8657237 = 8657448

Showing the first eight; more decompositions exist.
