Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649738, here are decompositions:

17 + 8649721 = 8649738
47 + 8649691 = 8649738
61 + 8649677 = 8649738
67 + 8649671 = 8649738
101 + 8649637 = 8649738
109 + 8649629 = 8649738
127 + 8649611 = 8649738
157 + 8649581 = 8649738

Showing the first eight; more decompositions exist.
