Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82868, here are decompositions:
- 31 + 82837 = 82868
- 109 + 82759 = 82868
- 139 + 82729 = 82868
- 211 + 82657 = 82868
- 277 + 82591 = 82868
- 307 + 82561 = 82868
- 337 + 82531 = 82868
- 397 + 82471 = 82868
Showing the first eight; more decompositions exist.
