Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65536, here are decompositions:

17 + 65519 = 65536
89 + 65447 = 65536
113 + 65423 = 65536
179 + 65357 = 65536
227 + 65309 = 65536
269 + 65267 = 65536
353 + 65183 = 65536
389 + 65147 = 65536

Showing the first eight; more decompositions exist.
