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.
