Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736986, here are decompositions:

43 + 8736943 = 8736986
67 + 8736919 = 8736986
79 + 8736907 = 8736986
103 + 8736883 = 8736986
199 + 8736787 = 8736986
283 + 8736703 = 8736986
439 + 8736547 = 8736986
457 + 8736529 = 8736986

Showing the first eight; more decompositions exist.
