LP Decay For Silver?

I was wondering if you don't play ranked games for a while, does you LP decay? I'm at Silver 5 with 43LP, but I want to take a break from ranked due to my raging at people as a result of ranked. I don't want to really "maintain" my rank during the time I'm "resting" from ranked . So, does LP decay or no if I don't play ranked for an extended period of time?
