Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3964, here are decompositions:
- 17 + 3947 = 3964
- 41 + 3923 = 3964
- 47 + 3917 = 3964
- 53 + 3911 = 3964
- 83 + 3881 = 3964
- 101 + 3863 = 3964
- 113 + 3851 = 3964
- 131 + 3833 = 3964
Showing the first eight; more decompositions exist.
