That's the model of photon, not the photon itself. A mathematical photon cannot decay. What prevents a photon from hitting a quantum bump on its way between galaxies and become an electron?

Indeed ultra high energy photons "decay" by interacting with the CMB.

Using the word “decay” to include that feels like it can’t be right.

But I’m not a proper physicist, just an amateur.

Yeah, you're right, it's not the right word at all!
