Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3874, here are decompositions:
- 11 + 3863 = 3874
- 23 + 3851 = 3874
- 41 + 3833 = 3874
- 53 + 3821 = 3874
- 71 + 3803 = 3874
- 107 + 3767 = 3874
- 113 + 3761 = 3874
- 173 + 3701 = 3874
Showing the first eight; more decompositions exist.
