Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607986, here are decompositions:

43 + 8607943 = 8607986
73 + 8607913 = 8607986
103 + 8607883 = 8607986
313 + 8607673 = 8607986
349 + 8607637 = 8607986
523 + 8607463 = 8607986
577 + 8607409 = 8607986
613 + 8607373 = 8607986

Showing the first eight; more decompositions exist.
