Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3972, here are decompositions:
- 5 + 3967 = 3972
- 29 + 3943 = 3972
- 41 + 3931 = 3972
- 43 + 3929 = 3972
- 53 + 3919 = 3972
- 61 + 3911 = 3972
- 83 + 3889 = 3972
- 109 + 3863 = 3972
Showing the first eight; more decompositions exist.
