Inspired by these series of puzzles, tell me a correct way by which adding 22 to 4 will give either 495 or 505.

As in the other puzzles, these numbers are all expressed in base 10.

I think you get these answers by

Converting each of the numbers to a letter of the alphabet with the convention 1=A, 2=B, etc, so that 4=D and 22=V.

Then, concatenate the letters so that you obtain either DV or VD and interpret the result as a Roman numeral so
DV=505 and VD could perhaps be interpreted as 495.
