Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724656, here are decompositions:

7 + 8724649 = 8724656
13 + 8724643 = 8724656
37 + 8724619 = 8724656
67 + 8724589 = 8724656
97 + 8724559 = 8724656
163 + 8724493 = 8724656
337 + 8724319 = 8724656
373 + 8724283 = 8724656

Showing the first eight; more decompositions exist.
