Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3948, here are decompositions:
- 5 + 3943 = 3948
- 17 + 3931 = 3948
- 19 + 3929 = 3948
- 29 + 3919 = 3948
- 31 + 3917 = 3948
- 37 + 3911 = 3948
- 41 + 3907 = 3948
- 59 + 3889 = 3948
Showing the first eight; more decompositions exist.
