Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630272, here are decompositions:

3 + 8630269 = 8630272
23 + 8630249 = 8630272
29 + 8630243 = 8630272
41 + 8630231 = 8630272
71 + 8630201 = 8630272
113 + 8630159 = 8630272
269 + 8630003 = 8630272
311 + 8629961 = 8630272

Showing the first eight; more decompositions exist.
