If I understand you correctly and remember your original rule, then I
think you have it backward.  If you are changing the destination, you
probably want to change it from the public address to the private
address:

iptables -t nat -A PREROUTING -d 5.6.7.8 -p 6 --dport 8080 -j DNAT
--to-destination 192.168.x.x:80

Remember to ensure that traffic to 192.168.x.x:80 is allowed on the
FORWARD chain and that the NAT gateway responds to ARPs for 5.6.7.8 -
