Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8696720, here are decompositions:

7 + 8696713 = 8696720
31 + 8696689 = 8696720
103 + 8696617 = 8696720
139 + 8696581 = 8696720
199 + 8696521 = 8696720
283 + 8696437 = 8696720
313 + 8696407 = 8696720
337 + 8696383 = 8696720

Showing the first eight; more decompositions exist.
