Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43878, here are decompositions:
- 11 + 43867 = 43878
- 89 + 43789 = 43878
- 97 + 43781 = 43878
- 101 + 43777 = 43878
- 157 + 43721 = 43878
- 167 + 43711 = 43878
- 227 + 43651 = 43878
- 229 + 43649 = 43878
Showing the first eight; more decompositions exist.
