Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649386, here are decompositions:

3 + 8649383 = 8649386
19 + 8649367 = 8649386
37 + 8649349 = 8649386
43 + 8649343 = 8649386
103 + 8649283 = 8649386
199 + 8649187 = 8649386
283 + 8649103 = 8649386
307 + 8649079 = 8649386

Showing the first eight; more decompositions exist.
