In the middle of 97 insert (97 - 1) and you get 9967, which is
also prime. Put (97 - 1) in the middle of 9967 and you get
999667, which is another prime. Put (97 - 1) in the middle again
and you get 99996667, yet another prime. After inserting
(97 - 1) in the middle once more, it is left for the prime curiologist to
find the factors of 9999966667. [Honaker]
