Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657224, here are decompositions:

3 + 8657221 = 8657224
101 + 8657123 = 8657224
113 + 8657111 = 8657224
353 + 8656871 = 8657224
491 + 8656733 = 8657224
503 + 8656721 = 8657224
557 + 8656667 = 8657224
647 + 8656577 = 8657224

Showing the first eight; more decompositions exist.
