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.
