At FL 350 the right engine rolled back. The appropriate enroute emergency procedures and Quick Reference Handbook (QRH) procedures were conducted. The engine responded to throttle movement at FL245 and I leveled at FL240. An uneventful; overweight; 2 engine landing ensued.
At FL350 Instrument Meteorological Conditions (IMC) TEMP -48 C Right engine Engine Pressure Ratio (EPR) indicated 1.90 +; all other engine indications rolled back to what appeared to be idle thrust. Engine anti-ice off at time of rollback(-48C OAT). Ran Quick Reference Handbook (QRH) checklist. Engine Anti-ice engaged as we began our descent off the airway.
