Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182816, here are decompositions:

3 + 182813 = 182816
13 + 182803 = 182816
37 + 182779 = 182816
43 + 182773 = 182816
103 + 182713 = 182816
157 + 182659 = 182816
163 + 182653 = 182816
199 + 182617 = 182816

Showing the first eight; more decompositions exist.
