Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624666, here are decompositions:

67 + 8624599 = 8624666
163 + 8624503 = 8624666
283 + 8624383 = 8624666
313 + 8624353 = 8624666
487 + 8624179 = 8624666
607 + 8624059 = 8624666
643 + 8624023 = 8624666
727 + 8623939 = 8624666

Showing the first eight; more decompositions exist.
