$\displaystyle \int_{0}^{-\infty} \left [ 2^{at} \zeta(bt) - 2^{c-dt} \zeta(t) \right ] \ dt$

If $$S = \log_{2}{e} - \log_{4}{e} + \log_{6}{e} - \log_{8}{e} \ldots$$ can be expressed as the integral above for positive integers $$a,b,c,d$$ are positive integers, find the value of $$200(a^2 + b^2 + c^2 - \sqrt{8d})$$.
