Instead of putting the address on the building, put in extra nodes where
the entrances with the different addresses are and tag them with the
address. You can re-use nodes from the building outline if you want to.
This would work for the example you mentioned above.

If you actually have different addresses *on the same entrance*, it wont
work. I have seen this a few times that maybe there used to be two
buildings, one number 4 and one number 6 and now there is only one and
it is called 4-6. In that case you can tag addr:housenumber=4-6. But
this wouldn't work if you have different street names. In that case you
can probably put two nodes right next to each other. It shouldn't happen
often, anway.
