Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630388, here are decompositions:

97 + 8630291 = 8630388
139 + 8630249 = 8630388
149 + 8630239 = 8630388
157 + 8630231 = 8630388
181 + 8630207 = 8630388
197 + 8630191 = 8630388
211 + 8630177 = 8630388
229 + 8630159 = 8630388

Showing the first eight; more decompositions exist.
