Primality proof for n = 2298041:
<p>Take b = 3.
<p>b^(n-1) mod n = 1.
<p><a href=787.html>787 is prime.</a>
<br>b^((n-1)/787)-1 mod n = 2240226, which is a unit, inverse 1632100.
<p><a href=73.html>73 is prime.</a>
<br>b^((n-1)/73)-1 mod n = 65535, which is a unit, inverse 1138904.
<p>(73 * 787) divides n-1.
<p>(73 * 787)^2 > n.
<p>n is prime by Pocklington's theorem.
