Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67858, here are decompositions:
- 5 + 67853 = 67858
- 29 + 67829 = 67858
- 101 + 67757 = 67858
- 107 + 67751 = 67858
- 149 + 67709 = 67858
- 179 + 67679 = 67858
- 227 + 67631 = 67858
- 239 + 67619 = 67858
Showing the first eight; more decompositions exist.
