Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700812, here are decompositions:

13 + 8700799 = 8700812
19 + 8700793 = 8700812
61 + 8700751 = 8700812
103 + 8700709 = 8700812
163 + 8700649 = 8700812
223 + 8700589 = 8700812
283 + 8700529 = 8700812
619 + 8700193 = 8700812

Showing the first eight; more decompositions exist.
