Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82790, here are decompositions:
- 3 + 82787 = 82790
- 31 + 82759 = 82790
- 61 + 82729 = 82790
- 67 + 82723 = 82790
- 139 + 82651 = 82790
- 157 + 82633 = 82790
- 181 + 82609 = 82790
- 199 + 82591 = 82790
Showing the first eight; more decompositions exist.
