While your code is very cool. A more powerful approach would probably be to extract the algorithms in Crandall's factor code which allows you to determine if any given number X is prime. You could call this algorithm in the loop for your specified range to solve the problem more quickly. :)

Of course, for very large X it will take much much longer to determine if X is prime.
