Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16838, here are decompositions:
- 7 + 16831 = 16838
- 79 + 16759 = 16838
- 97 + 16741 = 16838
- 109 + 16729 = 16838
- 139 + 16699 = 16838
- 181 + 16657 = 16838
- 271 + 16567 = 16838
- 277 + 16561 = 16838
Showing the first eight; more decompositions exist.
