For a problem in recreational math I am testing numbers of
magnitude around 10^1400 whether they are prime or not.
It takes about two and half an hour per number when I use
the standard isprime() Funktion.

Are there ways inside Maple (I use V) to get the results faster?

Wolfram Alpha doesn's accept large numbers like that without
fee. Are there any sources in the web accepting large numbers
that are free and reliable?

Cheers,
Rainer
