Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3944, here are decompositions:
- 13 + 3931 = 3944
- 37 + 3907 = 3944
- 67 + 3877 = 3944
- 97 + 3847 = 3944
- 151 + 3793 = 3944
- 211 + 3733 = 3944
- 271 + 3673 = 3944
- 307 + 3637 = 3944
Showing the first eight; more decompositions exist.
