Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167772, here are decompositions:
- 13 + 167759 = 167772
- 43 + 167729 = 167772
- 61 + 167711 = 167772
- 89 + 167683 = 167772
- 109 + 167663 = 167772
- 131 + 167641 = 167772
- 139 + 167633 = 167772
- 149 + 167623 = 167772
Showing the first eight; more decompositions exist.
