Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670828, here are decompositions:

17 + 8670811 = 8670828
37 + 8670791 = 8670828
149 + 8670679 = 8670828
191 + 8670637 = 8670828
239 + 8670589 = 8670828
269 + 8670559 = 8670828
277 + 8670551 = 8670828
337 + 8670491 = 8670828

Showing the first eight; more decompositions exist.
