In my program, only A and B were necessarily getting larger in sum (actually the square roots). C would take up whatever slack. A formal proof would have to include what possible factors C could have as a result and limits on the smallness of C (can't be 1, 2, 3, 4, but could be 5, 6, ... as necessary to fill in for large A and B).
