Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13904, here are decompositions:
- 3 + 13901 = 13904
- 31 + 13873 = 13904
- 73 + 13831 = 13904
- 97 + 13807 = 13904
- 181 + 13723 = 13904
- 193 + 13711 = 13904
- 211 + 13693 = 13904
- 223 + 13681 = 13904
Showing the first eight; more decompositions exist.
