Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82668, here are decompositions:
- 11 + 82657 = 82668
- 17 + 82651 = 82668
- 59 + 82609 = 82668
- 67 + 82601 = 82668
- 97 + 82571 = 82668
- 101 + 82567 = 82668
- 107 + 82561 = 82668
- 109 + 82559 = 82668
Showing the first eight; more decompositions exist.
