Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671986, here are decompositions:

5 + 8671981 = 8671986
7 + 8671979 = 8671986
19 + 8671967 = 8671986
67 + 8671919 = 8671986
79 + 8671907 = 8671986
149 + 8671837 = 8671986
277 + 8671709 = 8671986
317 + 8671669 = 8671986

Showing the first eight; more decompositions exist.
