Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16688, here are decompositions:

31 + 16657 = 16688
37 + 16651 = 16688
127 + 16561 = 16688
211 + 16477 = 16688
241 + 16447 = 16688
271 + 16417 = 16688
277 + 16411 = 16688
307 + 16381 = 16688

Showing the first eight; more decompositions exist.
