Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66766, here are decompositions:
- 3 + 66763 = 66766
- 17 + 66749 = 66766
- 53 + 66713 = 66766
- 83 + 66683 = 66766
- 113 + 66653 = 66766
- 137 + 66629 = 66766
- 149 + 66617 = 66766
- 173 + 66593 = 66766
Showing the first eight; more decompositions exist.
