Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668818, here are decompositions:

5 + 8668813 = 8668818
17 + 8668801 = 8668818
19 + 8668799 = 8668818
79 + 8668739 = 8668818
97 + 8668721 = 8668818
107 + 8668711 = 8668818
131 + 8668687 = 8668818
181 + 8668637 = 8668818

Showing the first eight; more decompositions exist.
