A mathematician working on the application of algebraic topology is analyzing a closed, orientable surface. Suppose the Euler characteristic of the surface is given by the formula \(\chi = 2 - 2g\), where \(g\) is the genus of the surface. If the surface is a double torus (i.e., \(g = 2\)), what is its Euler characteristic?
