I also investigated this with gp, and I'm beginning to believe the statement as stated is false. To clarify, the sum I'm interested in is S(x)...

In case you were wondering about my estimate for \pi(x), I used that for every A > 0, we have \pi(x) = li(x) \left( 1 + O \left( \frac{1}{\log^A x} \right) \right) whenever x >= x(A) is...

I want to show that for x > 2, S(x) = \sum_{p \leq x} \log^2 x = x \log x + O \left( \frac{x}{\log x} \right). Using Stieltjes integration, I get to...

When I made the substitution I wound up with a log(log(n)) term in the denominator that I'm not sure how to get rid of. I tried estimating some more, but...
