What are they stuck to? Drywall?
Even 20 years back, they used silicone against the wall--often nothing at all between the counter top and the back splash---
Just a small bead of silicone where they meet---
Use a painters tool as a wedge/pry bar and pull off the back splash---wood shims can be used also---some polishing might be needed to clean up the newly exposed part.
