Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630398, here are decompositions:

11 + 8630387 = 8630398
107 + 8630291 = 8630398
149 + 8630249 = 8630398
167 + 8630231 = 8630398
191 + 8630207 = 8630398
197 + 8630201 = 8630398
239 + 8630159 = 8630398
281 + 8630117 = 8630398

Showing the first eight; more decompositions exist.
