Primality proof for n = 298407043007230668716584089637:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=5924666185313169299.html>5924666185313169299 is prime.</a>
<br>b^((n-1)/5924666185313169299)-1 mod n = 199777376438514578804965374316, which is a unit, inverse 155904965922011319053954941227.
<p>(5924666185313169299) divides n-1.
<p>(5924666185313169299)^2 > n.
<p>n is prime by Pocklington's theorem.
