Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3888, here are decompositions:
- 7 + 3881 = 3888
- 11 + 3877 = 3888
- 37 + 3851 = 3888
- 41 + 3847 = 3888
- 67 + 3821 = 3888
- 109 + 3779 = 3888
- 127 + 3761 = 3888
- 149 + 3739 = 3888
Showing the first eight; more decompositions exist.
