Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625916, here are decompositions:

3 + 8625913 = 8625916
83 + 8625833 = 8625916
107 + 8625809 = 8625916
227 + 8625689 = 8625916
317 + 8625599 = 8625916
389 + 8625527 = 8625916
449 + 8625467 = 8625916
557 + 8625359 = 8625916

Showing the first eight; more decompositions exist.
