Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16986, here are decompositions:
- 5 + 16981 = 16986
- 7 + 16979 = 16986
- 23 + 16963 = 16986
- 43 + 16943 = 16986
- 59 + 16927 = 16986
- 83 + 16903 = 16986
- 97 + 16889 = 16986
- 103 + 16883 = 16986
Showing the first eight; more decompositions exist.
