Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82570, here are decompositions:
- 3 + 82567 = 82570
- 11 + 82559 = 82570
- 41 + 82529 = 82570
- 71 + 82499 = 82570
- 83 + 82487 = 82570
- 101 + 82469 = 82570
- 107 + 82463 = 82570
- 113 + 82457 = 82570
Showing the first eight; more decompositions exist.
