Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66576, here are decompositions:
- 5 + 66571 = 66576
- 7 + 66569 = 66576
- 23 + 66553 = 66576
- 43 + 66533 = 66576
- 47 + 66529 = 66576
- 53 + 66523 = 66576
- 67 + 66509 = 66576
- 109 + 66467 = 66576
Showing the first eight; more decompositions exist.
