Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630628, here are decompositions:

29 + 8630599 = 8630628
37 + 8630591 = 8630628
109 + 8630519 = 8630628
137 + 8630491 = 8630628
151 + 8630477 = 8630628
179 + 8630449 = 8630628
211 + 8630417 = 8630628
241 + 8630387 = 8630628

Showing the first eight; more decompositions exist.
