Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13824, here are decompositions:
- 17 + 13807 = 13824
- 43 + 13781 = 13824
- 61 + 13763 = 13824
- 67 + 13757 = 13824
- 73 + 13751 = 13824
- 101 + 13723 = 13824
- 103 + 13721 = 13824
- 113 + 13711 = 13824
Showing the first eight; more decompositions exist.
