Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630428, here are decompositions:

11 + 8630417 = 8630428
41 + 8630387 = 8630428
137 + 8630291 = 8630428
179 + 8630249 = 8630428
197 + 8630231 = 8630428
227 + 8630201 = 8630428
251 + 8630177 = 8630428
269 + 8630159 = 8630428

Showing the first eight; more decompositions exist.
