Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615226, here are decompositions:

7 + 8615219 = 8615226
29 + 8615197 = 8615226
89 + 8615137 = 8615226
127 + 8615099 = 8615226
163 + 8615063 = 8615226
239 + 8614987 = 8615226
313 + 8614913 = 8615226
337 + 8614889 = 8615226

Showing the first eight; more decompositions exist.
