Primality proof for n = 9610823281:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=3931.html>3931 is prime.</a>
<br>b^((n-1)/3931)-1 mod n = 8940185587, which is a unit, inverse 9486107731.
<p><a href=167.html>167 is prime.</a>
<br>b^((n-1)/167)-1 mod n = 3907843733, which is a unit, inverse 9481220143.
<p>(167 * 3931) divides n-1.
<p>(167 * 3931)^2 > n.
<p>n is prime by Pocklington's theorem.
