Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4006, here are decompositions:
- 3 + 4003 = 4006
- 5 + 4001 = 4006
- 17 + 3989 = 4006
- 59 + 3947 = 4006
- 83 + 3923 = 4006
- 89 + 3917 = 4006
- 173 + 3833 = 4006
- 227 + 3779 = 4006
Showing the first eight; more decompositions exist.
