Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718226, here are decompositions:

5 + 8718221 = 8718226
29 + 8718197 = 8718226
113 + 8718113 = 8718226
137 + 8718089 = 8718226
227 + 8717999 = 8718226
233 + 8717993 = 8718226
239 + 8717987 = 8718226
263 + 8717963 = 8718226

Showing the first eight; more decompositions exist.
