Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16880, here are decompositions:

37 + 16843 = 16880
139 + 16741 = 16880
151 + 16729 = 16880
181 + 16699 = 16880
223 + 16657 = 16880
229 + 16651 = 16880
277 + 16603 = 16880
307 + 16573 = 16880

Showing the first eight; more decompositions exist.
