Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683988, here are decompositions:

307 + 8683681 = 8683988
331 + 8683657 = 8683988
349 + 8683639 = 8683988
457 + 8683531 = 8683988
661 + 8683327 = 8683988
727 + 8683261 = 8683988
739 + 8683249 = 8683988
751 + 8683237 = 8683988

Showing the first eight; more decompositions exist.
