Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111816, here are decompositions:

17 + 111799 = 111816
37 + 111779 = 111816
43 + 111773 = 111816
83 + 111733 = 111816
149 + 111667 = 111816
157 + 111659 = 111816
163 + 111653 = 111816
179 + 111637 = 111816

Showing the first eight; more decompositions exist.
