My opinion is that this is the wrong problem to solve. Assuming the
example is simplified and there is in fact reason to break lines, it
should be

    variable = 12 +
        4 * 18 * 99 +
        8

or

    variable = 12
        + 4 * 18 * 99
        + 8

or maybe

    variable =
        12 + 4 * 18 * 99 + 8

i.e. prefer breaking lines higher in the AST.

Also, this style only makes sense if tab characters are not used.
Otherwise, the alignment will break for users whose tab width differs.
(Emacs’s source code suffers from this a lot.)
