Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623986, here are decompositions:

17 + 8623969 = 8623986
23 + 8623963 = 8623986
47 + 8623939 = 8623986
83 + 8623903 = 8623986
89 + 8623897 = 8623986
103 + 8623883 = 8623986
139 + 8623847 = 8623986
179 + 8623807 = 8623986

Showing the first eight; more decompositions exist.
