Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3858, here are decompositions:
- 5 + 3853 = 3858
- 7 + 3851 = 3858
- 11 + 3847 = 3858
- 37 + 3821 = 3858
- 61 + 3797 = 3858
- 79 + 3779 = 3858
- 89 + 3769 = 3858
- 97 + 3761 = 3858
Showing the first eight; more decompositions exist.
