Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628646, here are decompositions:

3 + 8628643 = 8628646
17 + 8628629 = 8628646
23 + 8628623 = 8628646
167 + 8628479 = 8628646
197 + 8628449 = 8628646
239 + 8628407 = 8628646
263 + 8628383 = 8628646
269 + 8628377 = 8628646

Showing the first eight; more decompositions exist.
