Doing a little bit of research, these primes are called “Proth Primes”. We also have the Prime Gap Equation which when writing in TEX, I accidentally forgot to add 2 to the RHS. Here is the clean version.

I mentioned this equation on three or four other threads I believe (Conjectures R Us, Prime Gap News, Predict M50/M51, etc) for I was trying to find a proof. Does anyone have a proof of this equation?
