Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56816, here are decompositions:

3 + 56813 = 56816
7 + 56809 = 56816
37 + 56779 = 56816
43 + 56773 = 56816
79 + 56737 = 56816
103 + 56713 = 56816
157 + 56659 = 56816
283 + 56533 = 56816

Showing the first eight; more decompositions exist.
