  (and (fboundp symbol)
       (let ((function-name (symbol-name symbol)))
         (and (string-match "-mode\\'" function-name)
              (not (string-match "\\`turn-\\(on\\|off\\)-"
                                 function-name))))
       (not (assq symbol minor-mode-alist))))

You could use this together with `mapatoms' to find all major modes.
