You can separate the digitizer from the lcd with a thin flat pry tool. The adhesive is not that strong and you don't need heat but you can use a little if it makes it easier for you. You don't even have to reapply any adhesive if you don't want to given the fact that the tray that holds the main board and the main board both push down on the screen and dig to hold it in place, the adhesive seemed more like a precaution on Nintendos part. 2 separate parts = cheaper repair in your case. Hope this helps!
