Unclear what you are asking for exactly. With $P(s)=\sum_{p^k}p^{1-sk}=\sum_p \frac{p^{1-s}}{1-p^{-s}}$ $$\sum_{n\ge 1} n^{-s}\sum_{p^k| n} p = \zeta(s)P(s)$$
$$\sum_{n\ge 1} n^{-s}\mu(n)\sum_{p^k| n} p = \sum_{p^k} p \sum_{n\ge 1} (p^k n)^{-s}\mu(p^k n)$$ $$=-\sum_p p \sum_{n\ge 1,p\,\nmid \,n} (p n)^{-s}\mu(n) = -\sum_p p \frac{p^{-s}}{(1-p^{-s})\zeta(s)}= -\frac{P(s)}{\zeta(s)}$$
