I'll tell you how. In order to see how newtonian gravity can bend the trajectory of a photon, relativists fake it. They magically tranform a photon with energy E into a particle with mass m = E/2c^2, it is saying half the mass in E = mc^2. Then, relativists assume that particle passes by the massive body from infinity travelling locally at c, and then they can apply newtonian gravity to see how its trajectory is deflected into a hyperbolic one. As a result there is a deflection angle twice the observed one. A particle with mass m = E/c^2, travelling locally at c from infinity, would be deflected in the correct angle, under newtonian gravity.
