Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630448, here are decompositions:

5 + 8630443 = 8630448
31 + 8630417 = 8630448
61 + 8630387 = 8630448
137 + 8630311 = 8630448
157 + 8630291 = 8630448
179 + 8630269 = 8630448
199 + 8630249 = 8630448
241 + 8630207 = 8630448

Showing the first eight; more decompositions exist.
