Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630, here are decompositions:

3 + 8627 = 8630
7 + 8623 = 8630
31 + 8599 = 8630
67 + 8563 = 8630
103 + 8527 = 8630
109 + 8521 = 8630
163 + 8467 = 8630
199 + 8431 = 8630

Showing the first eight; more decompositions exist.
