Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16946, here are decompositions:
- 3 + 16943 = 16946
- 19 + 16927 = 16946
- 43 + 16903 = 16946
- 67 + 16879 = 16946
- 103 + 16843 = 16946
- 199 + 16747 = 16946
- 313 + 16633 = 16946
- 373 + 16573 = 16946
Showing the first eight; more decompositions exist.
