Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16906, here are decompositions:
- 3 + 16903 = 16906
- 5 + 16901 = 16906
- 17 + 16889 = 16906
- 23 + 16883 = 16906
- 83 + 16823 = 16906
- 233 + 16673 = 16906
- 257 + 16649 = 16906
- 353 + 16553 = 16906
Showing the first eight; more decompositions exist.
