Narrative:

Approximately 45 mins after departing at FL350; the right engine hydraulic pump light illuminated with the associated right hydraulic engine pump EICAS message. Performed the QRH procedure and turned off the affected pump switch. No loss of system quantity or pressure occurred. Decided to return to departure airport. Landed and made an aircraft change. Supplemental information from acn 764331: did not declare emergency; we did not need priority handling and all hydraulic systems were normal due to the back-up elec pump. We also needed to reduce our landing weight to avoid overweight landing.
