Hi,
The idea that it is going slightly past center, 231 degrees, really isn't a concern. Do you notice this at all times or is it after climbing a hill or while sitting in traffic? Also, have you confirmed the coolant is full?
Also, have you ever serviced the cooling system? As mentioned, at that temperature I'm not really too concerned because it isn't out of the ordinary. If it slowly continues to climb, then I would recommend flushing the cooling system and replacing the thermostat.
If you do decide to do that, here are two links that explain the process:

It's a good idea to do them at the same time so you don't waste coolant.
Let me know if this helps or if you have questions.
Take care,
Joe
