I have found waxed dental floss (flavoured or not) works great. First remove all the inside and outside silicone (I will pile up and cause the floss to brake). start with the one panel at a time. I like to start with the small side panels. Slowly work the floss through. Keep running the flos through like doing your teeth. ever so often might have to clean the wax out. the floss will brake alot but once you fine the feel for it it cut eazy. Half way down the cut go to the opposite panel do the same. Then you can use a razor blade to slightly wedge the panels. Then continue with the seams. Once the one panel seams are completely cut then carefull rock that panel back and forth. While rocking you can run a razor blade or zip knife alone the seal. then repeat with the other panels. Keep in mined patience it will come apart. One note wear glove just in case. Good luck.
