777 Qs

I was doing some reading on the 777-200 vs the 777-300 and something didn't quite make sense.

According to the info, both aircraft have the RR Trent 892 engines (at least for CX' a/c); however, the thrust for the -200 was 84000lbs, while the -300 has 92000lbs. How can the thrust be different if the engines are the exact same?

Also, the same source quoted the -200's range as 7150nm, while the -300's range as only 5200nm. This doesn't seem right at all. Wouldnt the -300 have the higher range?

Thanks in advance.
