Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670986, here are decompositions:

43 + 8670943 = 8670986
67 + 8670919 = 8670986
277 + 8670709 = 8670986
283 + 8670703 = 8670986
307 + 8670679 = 8670986
349 + 8670637 = 8670986
367 + 8670619 = 8670986
397 + 8670589 = 8670986

Showing the first eight; more decompositions exist.
