Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3996, here are decompositions:
- 7 + 3989 = 3996
- 29 + 3967 = 3996
- 53 + 3943 = 3996
- 67 + 3929 = 3996
- 73 + 3923 = 3996
- 79 + 3917 = 3996
- 89 + 3907 = 3996
- 107 + 3889 = 3996
Showing the first eight; more decompositions exist.
