Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649566, here are decompositions:

97 + 8649469 = 8649566
103 + 8649463 = 8649566
157 + 8649409 = 8649566
199 + 8649367 = 8649566
223 + 8649343 = 8649566
283 + 8649283 = 8649566
313 + 8649253 = 8649566
379 + 8649187 = 8649566

Showing the first eight; more decompositions exist.
