Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3856, here are decompositions:
- 3 + 3853 = 3856
- 5 + 3851 = 3856
- 23 + 3833 = 3856
- 53 + 3803 = 3856
- 59 + 3797 = 3856
- 89 + 3767 = 3856
- 137 + 3719 = 3856
- 179 + 3677 = 3856
Showing the first eight; more decompositions exist.
