\[\large \sum_{n=1}^\infty \dfrac{\Omega(n)\tau(n)}{n^2}=\dfrac{\pi^a}{b} \sum_{p \text{ prime}}^\infty \dfrac{1}{p^2-1}\]

If the equation above holds true for integer constants \(a\) and \(b\), find \(a+b\).

**Notations**:

\(\Omega(n)\) counts the number of prime factors of \(n\) (with multiplicity)

\(\tau(n)\) counts the number of divisors of \(n\).
