Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16768, here are decompositions:

5 + 16763 = 16768
107 + 16661 = 16768
137 + 16631 = 16768
149 + 16619 = 16768
239 + 16529 = 16768
281 + 16487 = 16768
317 + 16451 = 16768
347 + 16421 = 16768

Showing the first eight; more decompositions exist.
