Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630640, here are decompositions:

41 + 8630599 = 8630640
47 + 8630593 = 8630640
149 + 8630491 = 8630640
157 + 8630483 = 8630640
163 + 8630477 = 8630640
191 + 8630449 = 8630640
197 + 8630443 = 8630640
223 + 8630417 = 8630640

Showing the first eight; more decompositions exist.
