Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655630, here are decompositions:

7 + 8655623 = 8655630
19 + 8655611 = 8655630
103 + 8655527 = 8655630
173 + 8655457 = 8655630
197 + 8655433 = 8655630
227 + 8655403 = 8655630
229 + 8655401 = 8655630
281 + 8655349 = 8655630

Showing the first eight; more decompositions exist.
