Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630666, here are decompositions:

3 + 8630663 = 8630666
13 + 8630653 = 8630666
19 + 8630647 = 8630666
67 + 8630599 = 8630666
73 + 8630593 = 8630666
223 + 8630443 = 8630666
397 + 8630269 = 8630666
487 + 8630179 = 8630666

Showing the first eight; more decompositions exist.
