Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168726, here are decompositions:
- 7 + 168719 = 168726
- 13 + 168713 = 168726
- 29 + 168697 = 168726
- 53 + 168673 = 168726
- 83 + 168643 = 168726
- 97 + 168629 = 168726
- 109 + 168617 = 168726
- 127 + 168599 = 168726
Showing the first eight; more decompositions exist.
