Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3958, here are decompositions:
- 11 + 3947 = 3958
- 29 + 3929 = 3958
- 41 + 3917 = 3958
- 47 + 3911 = 3958
- 107 + 3851 = 3958
- 137 + 3821 = 3958
- 179 + 3779 = 3958
- 191 + 3767 = 3958
Showing the first eight; more decompositions exist.
