You could do this in you httpd.conf but John said this before. Another idea:

If you want the Apache listen to port 80 by some reason and want to make the 
server accessible thru port 87 too, you could setup port forwarding with 
iptables.

I think it goes like this:

/sbin/iptables -t nat -I PREROUTING -p tcp -i eth0 --dport 87 -j DNAT --to 
192.168.0.1:80

You will find more information here or at google when searching for "iptables 
port forwarding howto":
