Narrative:

We were on an IFR flight plan to boise (boi). As we were crossing the mld VOR center came on and advised us that there was traffic about 5 miles away and low. I came back and said that I had them in sight. Initially it looked like the traffic was flying away from us [so] I said that they won't be a factor. Right after I said that the traffic turned and started coming straight for us. Center advised that they were coming for us at the same altitude. I advised center that we were going to maneuver away from the oncoming traffic and they passed right off of our right side same altitude. After they passed by center asked if we can return on course. We advised that we could and said that it was a small aircraft that passed by us.
