Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3992, here are decompositions:
- 3 + 3989 = 3992
- 61 + 3931 = 3992
- 73 + 3919 = 3992
- 103 + 3889 = 3992
- 139 + 3853 = 3992
- 199 + 3793 = 3992
- 223 + 3769 = 3992
- 283 + 3709 = 3992
Showing the first eight; more decompositions exist.
