Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16928, here are decompositions:

7 + 16921 = 16928
97 + 16831 = 16928
181 + 16747 = 16928
199 + 16729 = 16928
229 + 16699 = 16928
271 + 16657 = 16928
277 + 16651 = 16928
367 + 16561 = 16928

Showing the first eight; more decompositions exist.
