Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167566, here are decompositions:
- 23 + 167543 = 167566
- 29 + 167537 = 167566
- 83 + 167483 = 167566
- 137 + 167429 = 167566
- 173 + 167393 = 167566
- 227 + 167339 = 167566
- 257 + 167309 = 167566
- 317 + 167249 = 167566
Showing the first eight; more decompositions exist.
