Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717278, here are decompositions:

5 + 8717273 = 8717278
107 + 8717171 = 8717278
257 + 8717021 = 8717278
281 + 8716997 = 8717278
359 + 8716919 = 8717278
389 + 8716889 = 8717278
461 + 8716817 = 8717278
509 + 8716769 = 8717278

Showing the first eight; more decompositions exist.
