Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659818, here are decompositions:

7 + 8659811 = 8659818
71 + 8659747 = 8659818
107 + 8659711 = 8659818
127 + 8659691 = 8659818
149 + 8659669 = 8659818
151 + 8659667 = 8659818
191 + 8659627 = 8659818
229 + 8659589 = 8659818

Showing the first eight; more decompositions exist.
