Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66658, here are decompositions:
- 5 + 66653 = 66658
- 29 + 66629 = 66658
- 41 + 66617 = 66658
- 71 + 66587 = 66658
- 89 + 66569 = 66658
- 149 + 66509 = 66658
- 167 + 66491 = 66658
- 191 + 66467 = 66658
Showing the first eight; more decompositions exist.
