Bob, you could also frag it very carefully with a hammer and chisel, and yes you will loose a few polyps but this type of coral is hardy to frag.
I have broke off similar corals with hammer and chisel before. Once you break the pieces you should give them a rinse in some saltwater for about half an hour before returning then into the main tank as they will release some mucus. Also be sure to use a clean chisel, this lessons the chance of the coral getting infections. When placed back into the tank, be sure to place the cut side of the coral into a high flow area of the tank for a week or two until it heals.
Some people may think this is an extreme method of fragging corals, although I have done this to many types of LPS corals including frogspawn, torch, brains, and even bubble corals with no losses. It's no different on a coral this way, than by natural methods such as storms or anchors or divers
