Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13800, here are decompositions:
- 11 + 13789 = 13800
- 19 + 13781 = 13800
- 37 + 13763 = 13800
- 41 + 13759 = 13800
- 43 + 13757 = 13800
- 71 + 13729 = 13800
- 79 + 13721 = 13800
- 89 + 13711 = 13800
Showing the first eight; more decompositions exist.
