Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700858, here are decompositions:

31 + 8700827 = 8700858
41 + 8700817 = 8700858
59 + 8700799 = 8700858
107 + 8700751 = 8700858
137 + 8700721 = 8700858
149 + 8700709 = 8700858
269 + 8700589 = 8700858
277 + 8700581 = 8700858

Showing the first eight; more decompositions exist.
