Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615238, here are decompositions:

7 + 8615231 = 8615238
19 + 8615219 = 8615238
41 + 8615197 = 8615238
61 + 8615177 = 8615238
89 + 8615149 = 8615238
101 + 8615137 = 8615238
139 + 8615099 = 8615238
251 + 8614987 = 8615238

Showing the first eight; more decompositions exist.
