Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609818, here are decompositions:

5 + 8609813 = 8609818
89 + 8609729 = 8609818
131 + 8609687 = 8609818
149 + 8609669 = 8609818
167 + 8609651 = 8609818
179 + 8609639 = 8609818
197 + 8609621 = 8609818
227 + 8609591 = 8609818

Showing the first eight; more decompositions exist.
