Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649960, here are decompositions:

23 + 8649937 = 8649960
31 + 8649929 = 8649960
73 + 8649887 = 8649960
79 + 8649881 = 8649960
89 + 8649871 = 8649960
103 + 8649857 = 8649960
107 + 8649853 = 8649960
113 + 8649847 = 8649960

Showing the first eight; more decompositions exist.
