Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3808, here are decompositions:
- 5 + 3803 = 3808
- 11 + 3797 = 3808
- 29 + 3779 = 3808
- 41 + 3767 = 3808
- 47 + 3761 = 3808
- 89 + 3719 = 3808
- 107 + 3701 = 3808
- 131 + 3677 = 3808
Showing the first eight; more decompositions exist.
