Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630458, here are decompositions:

41 + 8630417 = 8630458
71 + 8630387 = 8630458
167 + 8630291 = 8630458
227 + 8630231 = 8630458
251 + 8630207 = 8630458
257 + 8630201 = 8630458
281 + 8630177 = 8630458
509 + 8629949 = 8630458

Showing the first eight; more decompositions exist.
