Geocoding API components ignores street_number and subpremise

Question

I'm trying to request Geocoding API with components parameter but it ignores street_number and subpremise.

Here is my request URL:

https://maps.googleapis.com/maps/api/geocode/json?components=country:LT|locality:vilnius|route:boksto|street_number:1|subpremise:1

Both street_number and subpremise are double checked and must be valid, but the response looks like this:

Can anyone suggest what I'm doing wrong?
