Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82810, here are decompositions:
- 11 + 82799 = 82810
- 17 + 82793 = 82810
- 23 + 82787 = 82810
- 29 + 82781 = 82810
- 47 + 82763 = 82810
- 53 + 82757 = 82810
- 83 + 82727 = 82810
- 89 + 82721 = 82810
Showing the first eight; more decompositions exist.
