The fact that Central 46 had to sentence him to 20,000 years in Muken suggests two things. The first is they can't simply execute him, which means he's unkillable. The second is that they sentenced him to 20,000 years of imprisonment. That's almost ten times Yamamoto's lifespan. He definitely has to have eternal life as well.
