Of course these are falsifiable theories. They make predictions. These predictions may turn out to be wrong. If they are sufficiently wrong (either individually or cumulatively) then the theory will be scrapped.

As it happens, dark matter makes lots of predictions. For example, it predicts the shape of X-ray emission from galaxies. Another theory, MOND, makes slightly different predictions. Recently, observations showed that MOND was wrong in its prediction, while dark matter was right.

While this does not prove dark matter is right, it supports it, and seriously wounds MOND.
