Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630238, here are decompositions:

7 + 8630231 = 8630238
31 + 8630207 = 8630238
37 + 8630201 = 8630238
47 + 8630191 = 8630238
59 + 8630179 = 8630238
61 + 8630177 = 8630238
79 + 8630159 = 8630238
167 + 8630071 = 8630238

Showing the first eight; more decompositions exist.
