Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670656, here are decompositions:

3 + 8670653 = 8670656
19 + 8670637 = 8670656
37 + 8670619 = 8670656
67 + 8670589 = 8670656
73 + 8670583 = 8670656
97 + 8670559 = 8670656
103 + 8670553 = 8670656
157 + 8670499 = 8670656

Showing the first eight; more decompositions exist.
