Primality proof for n = 8995256861:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=3623.html>3623 is prime.</a>
<br>b^((n-1)/3623)-1 mod n = 6419724765, which is a unit, inverse 6319943534.
<p><a href=2887.html>2887 is prime.</a>
<br>b^((n-1)/2887)-1 mod n = 3551853849, which is a unit, inverse 3923286623.
<p>(2887 * 3623) divides n-1.
<p>(2887 * 3623)^2 > n.
<p>n is prime by Pocklington's theorem.
