Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686984, here are decompositions:

3 + 8686981 = 8686984
23 + 8686961 = 8686984
83 + 8686901 = 8686984
101 + 8686883 = 8686984
107 + 8686877 = 8686984
263 + 8686721 = 8686984
281 + 8686703 = 8686984
521 + 8686463 = 8686984

Showing the first eight; more decompositions exist.
