Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630402, here are decompositions:

163 + 8630239 = 8630402
211 + 8630191 = 8630402
223 + 8630179 = 8630402
229 + 8630173 = 8630402
283 + 8630119 = 8630402
331 + 8630071 = 8630402
373 + 8630029 = 8630402
421 + 8629981 = 8630402

Showing the first eight; more decompositions exist.
