Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38656, here are decompositions:

3 + 38653 = 38656
5 + 38651 = 38656
17 + 38639 = 38656
47 + 38609 = 38656
53 + 38603 = 38656
89 + 38567 = 38656
113 + 38543 = 38656
197 + 38459 = 38656

Showing the first eight; more decompositions exist.
