Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704656, here are decompositions:

5 + 8704651 = 8704656
43 + 8704613 = 8704656
47 + 8704609 = 8704656
67 + 8704589 = 8704656
89 + 8704567 = 8704656
97 + 8704559 = 8704656
109 + 8704547 = 8704656
157 + 8704499 = 8704656

Showing the first eight; more decompositions exist.
