Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16280, here are decompositions:

7 + 16273 = 16280
13 + 16267 = 16280
31 + 16249 = 16280
97 + 16183 = 16280
139 + 16141 = 16280
193 + 16087 = 16280
211 + 16069 = 16280
223 + 16057 = 16280

Showing the first eight; more decompositions exist.
