Actually there are roughly 1000 astartes chapters with each in the vicinity of 1000 members which leave somewhere around a million loyal astartes. Of course they are spread all over the galaxy and so are unable to bring their full weight anywhere. Due to the difficulty with corrupted geneseed the traitor astartes, even with the geneseed they manage to steal, are probably somewhat fewer in numberthan the loyalists. They are however mostly concentrated in a only a few areas (Eye of Terror, the Maelstrom etc) so they can bring more weight to any particular point when they unite.
