Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28768, here are decompositions:

17 + 28751 = 28768
71 + 28697 = 28768
107 + 28661 = 28768
137 + 28631 = 28768
149 + 28619 = 28768
197 + 28571 = 28768
227 + 28541 = 28768
251 + 28517 = 28768

Showing the first eight; more decompositions exist.
