Superprime Rib
==============

Butchering Farmer John's cows always yields the best prime rib. You
can tell prime ribs by looking at the digits lovingly stamped
across them, one by one, by FJ and the USDA. Farmer John ensures
that a purchaser of his prime ribs gets really prime ribs because
when sliced from the right, the numbers on the ribs continue to
stay prime right down to the last rib, e.g.:

     7  3  3  1

The set of ribs denoted by 7331 is prime; the three ribs 733 are
prime; the two ribs 73 are prime, and, of course, the last rib, 7,
is prime. The number 7331 is called a superprime of length 4.

Write a program that accepts a number N (1 <= N <= 8) of ribs and
prints all the superprimes of that length.

The number 1 (by itself) is not a prime number.
