Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66850, here are decompositions:
- 29 + 66821 = 66850
- 41 + 66809 = 66850
- 53 + 66797 = 66850
- 59 + 66791 = 66850
- 101 + 66749 = 66850
- 137 + 66713 = 66850
- 149 + 66701 = 66850
- 167 + 66683 = 66850
Showing the first eight; more decompositions exist.
