Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82560, here are decompositions:
- 11 + 82549 = 82560
- 29 + 82531 = 82560
- 31 + 82529 = 82560
- 53 + 82507 = 82560
- 61 + 82499 = 82560
- 67 + 82493 = 82560
- 73 + 82487 = 82560
- 89 + 82471 = 82560
Showing the first eight; more decompositions exist.
