The PW4000 engine (as used by UA) has been in service for a long time, in various forms
https://en.wikipedia.org/wiki/Pratt_%26_Whitney_PW4000
In 2000, over 2,000 PW4000 engines had accumulated over 40 million hours of service with 75 operators.[1] In 30 years between June 1987 and 2017, more than 2,500 engines have been delivered, logging more than 135 million flight hours.[2]
Those numbers were 20 years ago
