There will be a few ways I am sure. My first thoughts.
(1) Posterizing still leaves a bit of a messy image. Using Colors -> Info -> Colorcube Analysis shows 146 shades.
(2) A better way might be Colors -> Map -> Palette Map using a suitable palette. I will attach the one I used, might be useful (or not)
(3) I used gimp_gmic_qt see: http://www.gmic.eu to separate those.
(4) The layers with a couple of them visible.
