Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628916, here are decompositions:

3 + 8628913 = 8628916
17 + 8628899 = 8628916
59 + 8628857 = 8628916
137 + 8628779 = 8628916
239 + 8628677 = 8628916
269 + 8628647 = 8628916
293 + 8628623 = 8628916
467 + 8628449 = 8628916

Showing the first eight; more decompositions exist.
