A Composite Determination Problem (Posted on 2006-04-23)

Determine whether or not N is a composite number, where

N = 675*26²¹ + 677*26¹⁰ - 1

NOTE:
A prime number (or a prime) is a natural number that has exactly two (distinct) natural number divisors, which are 1 and the prime number itself. A composite number is a positive integer which has a positive divisor other than one or itself. By definition, every integer greater than one is either a prime number or a composite number. The numbers 0 and 1 are considered to be neither prime nor composite.
