That probably won't be very precise. A better option would be doing an advanced search, then select Structure Features -> Number of Entities as a protein query, select "protein" as entity type, and then a very wide interval starting with 2 (say, between 2 and 100). That returns 14453 hits if I click "result count". Then you can add search criteria to refine your search - in your case, Deposition->Deposit Date and then select the desired timespan will return what you're looking for.
