Prime numbers are not the same in the alternate reality that is Croneria, as they no longer represent numbers only divisible by 1 and itself. A prime number in Croneria is a number with a faxen amount of digits, but in Croneria, a faxen number is not a number divisible by a fax. A faxen number is a number in the fibonacci sequence (0,\ 1,\ 1,\ 2,\ 3,\ 5,\ 8,\ldots). The members of team starfax mess up often when determining if a number is prime or not, so they have turned to you for a program. Given an integer a (-999\,999 \le a \le 999\,999) output true if the number is prime, and false, if it is not.
