Just a note: the "pairwise" terms above depend on the effective Born radii,
which in turn depend on the positions of all atoms in the system. So, GB
theory is not pairwise decomposable in the sense that Coulomb's law is.
Various approximations can be used to get around this. And remember that any
decomposition is to be judged on its heuristic utility in understanding
trends, or in making simple predictions.
