Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13866, here are decompositions:
- 7 + 13859 = 13866
- 37 + 13829 = 13866
- 59 + 13807 = 13866
- 67 + 13799 = 13866
- 103 + 13763 = 13866
- 107 + 13759 = 13866
- 109 + 13757 = 13866
- 137 + 13729 = 13866
Showing the first eight; more decompositions exist.
