Given a function $f(x)$ ($x \in \mathbb{R}$) that satisfies $f(-x) = 8 - f(4 + x)$, and a function $g(x) = \frac{4x + 3}{x - 2}$, determine the value of $(x_1 + y_1) + (x_2 + y_2) + \ldots + (x_{168} + y_{168})$ where $P_i(x_i, y_i)$ ($i = 1, 2, \ldots, 168$) are the common points of the graphs of functions $f(x)$ and $g(x)$.
