Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13856, here are decompositions:
- 67 + 13789 = 13856
- 97 + 13759 = 13856
- 127 + 13729 = 13856
- 163 + 13693 = 13856
- 223 + 13633 = 13856
- 229 + 13627 = 13856
- 379 + 13477 = 13856
- 439 + 13417 = 13856
Showing the first eight; more decompositions exist.
