Primality proof for n = 479216833:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=5791.html>5791 is prime.</a>
<br>b^((n-1)/5791)-1 mod n = 130839220, which is a unit, inverse 355834915.
<p><a href=431.html>431 is prime.</a>
<br>b^((n-1)/431)-1 mod n = 478388572, which is a unit, inverse 321309679.
<p>(431 * 5791) divides n-1.
<p>(431 * 5791)^2 > n.
<p>n is prime by Pocklington's theorem.
