Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649916, here are decompositions:

5 + 8649911 = 8649916
29 + 8649887 = 8649916
47 + 8649869 = 8649916
59 + 8649857 = 8649916
113 + 8649803 = 8649916
227 + 8649689 = 8649916
239 + 8649677 = 8649916
293 + 8649623 = 8649916

Showing the first eight; more decompositions exist.
