Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630390, here are decompositions:

3 + 8630387 = 8630390
79 + 8630311 = 8630390
151 + 8630239 = 8630390
199 + 8630191 = 8630390
211 + 8630179 = 8630390
271 + 8630119 = 8630390
277 + 8630113 = 8630390
409 + 8629981 = 8630390

Showing the first eight; more decompositions exist.
