Sort of. You need to spend more time in the US than not, but even if you do 6 months every year, there's a high change you'll start to get tough questions when you try to reenter. Longer periods, it gets worse.
That said, the GC will only be taken away if (a) you give it up (you can be pressured into doing so though) or (b) an immigration judge takes it away (CBP can send your case to one if they think you are not living in the US)
This is why a reentry permit exists and that's what OP is talking about. It allows one to leave the country for two years and can be renewed (not guaranteed though).
