Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13826, here are decompositions:
- 19 + 13807 = 13826
- 37 + 13789 = 13826
- 67 + 13759 = 13826
- 97 + 13729 = 13826
- 103 + 13723 = 13826
- 139 + 13687 = 13826
- 157 + 13669 = 13826
- 193 + 13633 = 13826
Showing the first eight; more decompositions exist.
