Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167808, here are decompositions:
- 7 + 167801 = 167808
- 29 + 167779 = 167808
- 31 + 167777 = 167808
- 37 + 167771 = 167808
- 61 + 167747 = 167808
- 79 + 167729 = 167808
- 97 + 167711 = 167808
- 131 + 167677 = 167808
Showing the first eight; more decompositions exist.
