Problem 54700. Leyland Primes

A Leyland Number is defined as a number of the form - x^y + y^x, or, x^y - y^x (x,y)>1
Given an array of numbers(>1), check if the corresponding numbers are Leyland Primes (Leyland Number and a prime) or not.
Example -
x=17, y=1 (2^3+3^2 and a prime)
x=1, y=0 (3^2-2^3 but not a prime)
x=2, y=0 (a prime but not a layland number)
x=8, y=0 (2^2+2^2 but not a prime)
x=37, y=1 (a prime but not a layland number)
x=7, y=1 (2^5-5^2 and a prime)
