If you're eating the rest of the egg raw, I doubt you're going to reduce your risk much by cooking the shells afterward. That's assuming you eat the shells right away. If not, then they should be stored or prepared properly. I think the body would assimilate them better if boiled and roasted, then ground to a powder, but I don't know, maybe people do that just to make it more palatable.
Also, eggs from free range chickens have a lower risk of salmonella than from caged chickens.
