Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11816, here are decompositions:

3 + 11813 = 11816
37 + 11779 = 11816
73 + 11743 = 11816
97 + 11719 = 11816
127 + 11689 = 11816
139 + 11677 = 11816
199 + 11617 = 11816
223 + 11593 = 11816

Showing the first eight; more decompositions exist.
