Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630478, here are decompositions:

29 + 8630449 = 8630478
61 + 8630417 = 8630478
167 + 8630311 = 8630478
229 + 8630249 = 8630478
239 + 8630239 = 8630478
271 + 8630207 = 8630478
277 + 8630201 = 8630478
359 + 8630119 = 8630478

Showing the first eight; more decompositions exist.
