Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3960, here are decompositions:
- 13 + 3947 = 3960
- 17 + 3943 = 3960
- 29 + 3931 = 3960
- 31 + 3929 = 3960
- 37 + 3923 = 3960
- 41 + 3919 = 3960
- 43 + 3917 = 3960
- 53 + 3907 = 3960
Showing the first eight; more decompositions exist.
