Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670818, here are decompositions:

7 + 8670811 = 8670818
67 + 8670751 = 8670818
109 + 8670709 = 8670818
139 + 8670679 = 8670818
151 + 8670667 = 8670818
181 + 8670637 = 8670818
199 + 8670619 = 8670818
229 + 8670589 = 8670818

Showing the first eight; more decompositions exist.
