Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66606, here are decompositions:
- 5 + 66601 = 66606
- 13 + 66593 = 66606
- 19 + 66587 = 66606
- 37 + 66569 = 66606
- 53 + 66553 = 66606
- 73 + 66533 = 66606
- 83 + 66523 = 66606
- 97 + 66509 = 66606
Showing the first eight; more decompositions exist.
