4021
This number is a prime.
In the beginning of "Hot Zone" (an episode of the science fiction television series Stargate Atlantis), during Dr. Zelenka's and McKay's game of "Prime or Not Prime," Dr. Zelenka erroneously answers that 4021 is not prime, even though it is.
(There is one curio for this number that has not yet been approved by an editor.)
