Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16286, here are decompositions:

13 + 16273 = 16286
19 + 16267 = 16286
37 + 16249 = 16286
97 + 16189 = 16286
103 + 16183 = 16286
199 + 16087 = 16286
223 + 16063 = 16286
229 + 16057 = 16286

Showing the first eight; more decompositions exist.
