Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630280, here are decompositions:

11 + 8630269 = 8630280
31 + 8630249 = 8630280
37 + 8630243 = 8630280
41 + 8630239 = 8630280
73 + 8630207 = 8630280
79 + 8630201 = 8630280
89 + 8630191 = 8630280
101 + 8630179 = 8630280

Showing the first eight; more decompositions exist.
