An example is: Normal/Grass, Normal/Fighting, Normal/Water, Normal/all other types that I hadn't listed with Normal. The same goes for all other types. This obviously excludes the type and itself.
Water, Psychic and Flying have each been paired with all the other types. They are the only types to have done so.
Hope I helped!
As of gen 8, psychic has been paired with every type.
List of Pokemon just to confirm
