Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3894, here are decompositions:
- 5 + 3889 = 3894
- 13 + 3881 = 3894
- 17 + 3877 = 3894
- 31 + 3863 = 3894
- 41 + 3853 = 3894
- 43 + 3851 = 3894
- 47 + 3847 = 3894
- 61 + 3833 = 3894
Showing the first eight; more decompositions exist.
