Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16868, here are decompositions:
- 37 + 16831 = 16868
- 109 + 16759 = 16868
- 127 + 16741 = 16868
- 139 + 16729 = 16868
- 211 + 16657 = 16868
- 307 + 16561 = 16868
- 349 + 16519 = 16868
- 421 + 16447 = 16868
Showing the first eight; more decompositions exist.
