Is the mass of a neutron = mass of proton + mass of electron + mass of antineutrino ?

The mass of the neutron is slightly higher than a proton, by approximately the mass of an electron.Is it right to say mass of neutron = mass of proton + mass of electron
In the standard model, we have predictions that are based on why they have the mass they have, but the predictions soon manifest themselves into a strange paradoxical question: Why these certain masses, and not the other quantities? In quantum physics this is called the Heirarchy Problem
