Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623818, here are decompositions:

11 + 8623807 = 8623818
17 + 8623801 = 8623818
19 + 8623799 = 8623818
31 + 8623787 = 8623818
61 + 8623757 = 8623818
67 + 8623751 = 8623818
89 + 8623729 = 8623818
97 + 8623721 = 8623818

Showing the first eight; more decompositions exist.
