Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628736, here are decompositions:

59 + 8628677 = 8628736
89 + 8628647 = 8628736
107 + 8628629 = 8628736
113 + 8628623 = 8628736
257 + 8628479 = 8628736
293 + 8628443 = 8628736
353 + 8628383 = 8628736
359 + 8628377 = 8628736

Showing the first eight; more decompositions exist.
