Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82782, here are decompositions:
- 19 + 82763 = 82782
- 23 + 82759 = 82782
- 53 + 82729 = 82782
- 59 + 82723 = 82782
- 61 + 82721 = 82782
- 83 + 82699 = 82782
- 131 + 82651 = 82782
- 149 + 82633 = 82782
Showing the first eight; more decompositions exist.
