Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3924, here are decompositions:
- 5 + 3919 = 3924
- 7 + 3917 = 3924
- 13 + 3911 = 3924
- 17 + 3907 = 3924
- 43 + 3881 = 3924
- 47 + 3877 = 3924
- 61 + 3863 = 3924
- 71 + 3853 = 3924
Showing the first eight; more decompositions exist.
