Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718256, here are decompositions:

5 + 8718251 = 8718256
59 + 8718197 = 8718256
167 + 8718089 = 8718256
257 + 8717999 = 8718256
263 + 8717993 = 8718256
269 + 8717987 = 8718256
293 + 8717963 = 8718256
317 + 8717939 = 8718256

Showing the first eight; more decompositions exist.
