Sounds like the usual weight discussion. The OP asked a question because he/she really didn't know. So answering the question is the first thing. Several have answered correctly ... you are overweight on the truck's GVWR. You are therefore not "technically" legal.
Now that the facts are understood, the debate (which involves a great deal of OPINION) is on. The problem with those who give you their opinion, is that they don't have to live with the consequences of those opinions, you do. You now know the facts and if you choose to operate overweight, at least it's a conscious decision of a fully formed individual.
As has been pointed out, this opens you to potential liability if a bad thing happens, but there is a low percentage of risk. Not zero, but not likely. Many people operate overweight, most because they are oblivious. Can't tell you the number of SRW 3/4 ton trucks pulling 5th wheels which are almost always overweight. There is another group that are overweight and they know they are, but chose to do so anyway. Not judging here, but as an adult you make your choices and accept the potential consequences.
IMO, you can operate your rig as you are, but just know that you are taking a chance (albeit a small one) by operating overweight.
