Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47808, here are decompositions:
- 11 + 47797 = 47808
- 17 + 47791 = 47808
- 29 + 47779 = 47808
- 31 + 47777 = 47808
- 67 + 47741 = 47808
- 71 + 47737 = 47808
- 97 + 47711 = 47808
- 107 + 47701 = 47808
Showing the first eight; more decompositions exist.
