Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13816, here are decompositions:
- 17 + 13799 = 13816
- 53 + 13763 = 13816
- 59 + 13757 = 13816
- 107 + 13709 = 13816
- 137 + 13679 = 13816
- 167 + 13649 = 13816
- 197 + 13619 = 13816
- 239 + 13577 = 13816
Showing the first eight; more decompositions exist.
