Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670720, here are decompositions:

7 + 8670713 = 8670720
11 + 8670709 = 8670720
17 + 8670703 = 8670720
41 + 8670679 = 8670720
53 + 8670667 = 8670720
67 + 8670653 = 8670720
83 + 8670637 = 8670720
101 + 8670619 = 8670720

Showing the first eight; more decompositions exist.
