Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167666, here are decompositions:
- 3 + 167663 = 167666
- 43 + 167623 = 167666
- 73 + 167593 = 167666
- 223 + 167443 = 167666
- 229 + 167437 = 167666
- 337 + 167329 = 167666
- 349 + 167317 = 167666
- 397 + 167269 = 167666
Showing the first eight; more decompositions exist.
