Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673986, here are decompositions:

73 + 8673913 = 8673986
109 + 8673877 = 8673986
283 + 8673703 = 8673986
439 + 8673547 = 8673986
487 + 8673499 = 8673986
523 + 8673463 = 8673986
613 + 8673373 = 8673986
787 + 8673199 = 8673986

Showing the first eight; more decompositions exist.
