Depending on how good you glued them, you can try cutting the fitting’s hub right at the end of the pipe, then make a cut through the hub just to the pipe. Then you can sometimes use a sharp screwdriver between the hub and the pipe to separate them. If it starts to separate, then the whole fitting often comes apart. If it takes a piece of the pipe in the process then you will have to cut the pipe off, but you would have had to do that anyway.
