Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686966, here are decompositions:

5 + 8686961 = 8686966
83 + 8686883 = 8686966
89 + 8686877 = 8686966
137 + 8686829 = 8686966
263 + 8686703 = 8686966
467 + 8686499 = 8686966
479 + 8686487 = 8686966
503 + 8686463 = 8686966

Showing the first eight; more decompositions exist.
