Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3892, here are decompositions:
- 3 + 3889 = 3892
- 11 + 3881 = 3892
- 29 + 3863 = 3892
- 41 + 3851 = 3892
- 59 + 3833 = 3892
- 71 + 3821 = 3892
- 89 + 3803 = 3892
- 113 + 3779 = 3892
Showing the first eight; more decompositions exist.
