Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630480, here are decompositions:

3 + 8630477 = 8630480
31 + 8630449 = 8630480
37 + 8630443 = 8630480
211 + 8630269 = 8630480
241 + 8630239 = 8630480
307 + 8630173 = 8630480
367 + 8630113 = 8630480
409 + 8630071 = 8630480

Showing the first eight; more decompositions exist.
