Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82858, here are decompositions:
- 11 + 82847 = 82858
- 47 + 82811 = 82858
- 59 + 82799 = 82858
- 71 + 82787 = 82858
- 101 + 82757 = 82858
- 131 + 82727 = 82858
- 137 + 82721 = 82858
- 239 + 82619 = 82858
Showing the first eight; more decompositions exist.
