Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645916, here are decompositions:

17 + 8645899 = 8645916
29 + 8645887 = 8645916
53 + 8645863 = 8645916
67 + 8645849 = 8645916
113 + 8645803 = 8645916
127 + 8645789 = 8645916
157 + 8645759 = 8645916
197 + 8645719 = 8645916

Showing the first eight; more decompositions exist.
