Note that runway 22L is the same as 4R, just with the opposite approach (from the other end, thus 180 degrees around). The 2 names appear at the corresponding ends of the runway.

In airport LFPG, runways 27R and 26R are strictly parallel.

You'll often get consecutively numbered runways that are parallel if there's already a C/L/R on that heading.

For example, DFW has 17L, 17C, 17R, 18L and 18R all with the same magnetic heading (176/356). Everything really is bigger in Texas. :)

And because the magnetic pole moves around over time, that means runways designations aren't constant. A few years ago, the runway at the airport where I fly had to change from 09/27 to 10/28 because of this.
