Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82680, here are decompositions:
- 23 + 82657 = 82680
- 29 + 82651 = 82680
- 47 + 82633 = 82680
- 61 + 82619 = 82680
- 67 + 82613 = 82680
- 71 + 82609 = 82680
- 79 + 82601 = 82680
- 89 + 82591 = 82680
Showing the first eight; more decompositions exist.
