Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91904, here are decompositions:
- 31 + 91873 = 91904
- 37 + 91867 = 91904
- 67 + 91837 = 91904
- 97 + 91807 = 91904
- 103 + 91801 = 91904
- 151 + 91753 = 91904
- 193 + 91711 = 91904
- 283 + 91621 = 91904
Showing the first eight; more decompositions exist.
