Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3946, here are decompositions:
- 3 + 3943 = 3946
- 17 + 3929 = 3946
- 23 + 3923 = 3946
- 29 + 3917 = 3946
- 83 + 3863 = 3946
- 113 + 3833 = 3946
- 149 + 3797 = 3946
- 167 + 3779 = 3946
Showing the first eight; more decompositions exist.
