It's interesting to compare that MTBF with the fact that there are about ten million airliner flights per year in the US. If we arbitrarily assume that the average airliner flight is two hours, that's a substantial number of failed engines per year, so obviously the redundancy on these craft really does work.
Incidentally, I went searching for airliner engine MTBF statistics and your comment was already near the top of Google's results.
Edit: erroneously said five million flights per year because I was looking at 2012 statistics for only the first six months. of the year. Oops.
