During cruise flight; it was noticed that the right engine Exhaust Gas Temperature (EGT) began to fluctuate and on occasion the EGT display for that engine would go blank and no EGT was displayed. All other engine parameters never changed. Dispatch was contacted via Satellite phone and the display problem was discussed with Maintenance and Dispatch. It was decided that the most prudent action was to return to the departure airport.A route was issued for a return to our departure airport and we advised ATC that we had a maintenance issue and we needed to return to the departure airport. ATC cleared our flight via a left turn direct to [our departure] airport. Later routing was to fix ZZZZZ then ZZZ VOR then the airport. We continuously monitored the right engine for any changes to other engine parameters should it become necessary to shut down the engine. An uneventful landing was accomplished and then taxied to the ramp.
