Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13864, here are decompositions:
- 5 + 13859 = 13864
- 23 + 13841 = 13864
- 83 + 13781 = 13864
- 101 + 13763 = 13864
- 107 + 13757 = 13864
- 113 + 13751 = 13864
- 167 + 13697 = 13864
- 173 + 13691 = 13864
Showing the first eight; more decompositions exist.
