Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168828, here are decompositions:
- 47 + 168781 = 168828
- 59 + 168769 = 168828
- 67 + 168761 = 168828
- 97 + 168731 = 168828
- 109 + 168719 = 168828
- 131 + 168697 = 168828
- 151 + 168677 = 168828
- 197 + 168631 = 168828
Showing the first eight; more decompositions exist.
