Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13868, here are decompositions:
- 37 + 13831 = 13868
- 61 + 13807 = 13868
- 79 + 13789 = 13868
- 109 + 13759 = 13868
- 139 + 13729 = 13868
- 157 + 13711 = 13868
- 181 + 13687 = 13868
- 199 + 13669 = 13868
Showing the first eight; more decompositions exist.
