Help - oil pan glued on

[Praxiss454]

Hi guys, I took the day off today to work on the truck. I've removed all the oil pan bolts but it won't budge. All around the edge there is what appears to be construction adhesive from a previous idiot owner.

Any ideas? I've tried using a putty knife to slide between the pan and block but with the engine in place it's not really helping. I'm afraid if I pry with a screwdriver I will dent the pan.
