Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718268, here are decompositions:

17 + 8718251 = 8718268
47 + 8718221 = 8718268
71 + 8718197 = 8718268
179 + 8718089 = 8718268
257 + 8718011 = 8718268
269 + 8717999 = 8718268
281 + 8717987 = 8718268
359 + 8717909 = 8718268

Showing the first eight; more decompositions exist.
