Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167856, here are decompositions:
- 47 + 167809 = 167856
- 79 + 167777 = 167856
- 97 + 167759 = 167856
- 109 + 167747 = 167856
- 127 + 167729 = 167856
- 173 + 167683 = 167856
- 179 + 167677 = 167856
- 193 + 167663 = 167856
Showing the first eight; more decompositions exist.
