Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13894, here are decompositions:
- 11 + 13883 = 13894
- 17 + 13877 = 13894
- 53 + 13841 = 13894
- 113 + 13781 = 13894
- 131 + 13763 = 13894
- 137 + 13757 = 13894
- 173 + 13721 = 13894
- 197 + 13697 = 13894
Showing the first eight; more decompositions exist.
