Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67668, here are decompositions:
- 17 + 67651 = 67668
- 37 + 67631 = 67668
- 61 + 67607 = 67668
- 67 + 67601 = 67668
- 79 + 67589 = 67668
- 89 + 67579 = 67668
- 101 + 67567 = 67668
- 109 + 67559 = 67668
Showing the first eight; more decompositions exist.
