Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13858, here are decompositions:
- 17 + 13841 = 13858
- 29 + 13829 = 13858
- 59 + 13799 = 13858
- 101 + 13757 = 13858
- 107 + 13751 = 13858
- 137 + 13721 = 13858
- 149 + 13709 = 13858
- 167 + 13691 = 13858
Showing the first eight; more decompositions exist.
