If you do split it or saw it, tie it belly side down to a 2 by 4 or 4 by 4 ,with little wood spacers in between the stave and the board, the length of the bow. This will keep it from getting to much back set or warping and still dry ok. Seal the ends and the back( if you remove the bark, and I recommend you do) with shellac or urathane to keep it from checking.
