Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16940, here are decompositions:
- 3 + 16937 = 16940
- 13 + 16927 = 16940
- 19 + 16921 = 16940
- 37 + 16903 = 16940
- 61 + 16879 = 16940
- 97 + 16843 = 16940
- 109 + 16831 = 16940
- 181 + 16759 = 16940
Showing the first eight; more decompositions exist.
