Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649764, here are decompositions:

3 + 8649761 = 8649764
7 + 8649757 = 8649764
43 + 8649721 = 8649764
61 + 8649703 = 8649764
73 + 8649691 = 8649764
103 + 8649661 = 8649764
127 + 8649637 = 8649764
313 + 8649451 = 8649764

Showing the first eight; more decompositions exist.
