Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32768, here are decompositions:

19 + 32749 = 32768
61 + 32707 = 32768
157 + 32611 = 32768
181 + 32587 = 32768
199 + 32569 = 32768
271 + 32497 = 32768
277 + 32491 = 32768
367 + 32401 = 32768

Showing the first eight; more decompositions exist.
