Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649718, here are decompositions:

29 + 8649689 = 8649718
41 + 8649677 = 8649718
47 + 8649671 = 8649718
89 + 8649629 = 8649718
107 + 8649611 = 8649718
137 + 8649581 = 8649718
197 + 8649521 = 8649718
227 + 8649491 = 8649718

Showing the first eight; more decompositions exist.
