When the prophecy said neither can live while the other survives, I think If harry survives Voldermort would be dead. and if Voldermort survives harry must have died. If harry is a horcrux then killing harry wouldn't be all that smart. Think about it If he kills harry he loses a horcruz if he loses to harry, harry being a horcrux would keep him alive.
Harry is not a Horcrux.
