But where are they coming from and going to if matter and energy cannot be destroyed?
From nothing. No new energy is created because virtual particles are always created in a way that does not disturb the total energy of the universe. For example, one positive particle and one negative particle. It can’t be any other way.

Think of particles as bundles of conserved quantities like charge, energy, mass, etc. In interactions, these quantities can be re-bundled into different particles—but the re-bundling isn’t creating or destroying the conserved quantities themselves.
