Primality proof for n = 300984643119527704331:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=59724981817583.html>59724981817583 is prime.</a>
<br>b^((n-1)/59724981817583)-1 mod n = 178580651581030377143, which is a unit, inverse 241084490235940532855.
<p>(59724981817583) divides n-1.
<p>(59724981817583)^2 > n.
<p>n is prime by Pocklington's theorem.
