Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670858, here are decompositions:

47 + 8670811 = 8670858
67 + 8670791 = 8670858
107 + 8670751 = 8670858
149 + 8670709 = 8670858
179 + 8670679 = 8670858
191 + 8670667 = 8670858
239 + 8670619 = 8670858
269 + 8670589 = 8670858

Showing the first eight; more decompositions exist.
