Jun 27, 2018 at 16:21 comment added Đào Thanh Oai I am sorry. I think your proof maybe false at (2)==> (1). I think (2) ==> $\pi(x+y) \le \pi(x)+\pi(y)+1$ ?
Jun 27, 2018 at 15:12 comment added GH from MO @Freeman: $(1)$ is believed to be false, because it contradicts the $k$-tuple conjecture. For a nice short explanation see en.wikipedia.org/wiki/…
Jun 27, 2018 at 4:25 comment added Đào Thanh Oai My comment is true? $P_{m+n}$ may $>>$ $P_{n+m-1}$ but $P_n+P_m \approx P_n+P_m-1$ ??
