Primality proof for n = 9350987:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=1201.html>1201 is prime.</a>
<br>b^((n-1)/1201)-1 mod n = 8760543, which is a unit, inverse 7529375.
<p><a href=229.html>229 is prime.</a>
<br>b^((n-1)/229)-1 mod n = 6867499, which is a unit, inverse 1732635.
<p>(229 * 1201) divides n-1.
<p>(229 * 1201)^2 > n.
<p>n is prime by Pocklington's theorem.
