We call a prime p$p$ "good" if there is $0<k<\log p$ with $2kp+1$ prime. What is the asymptotic density of good primes.

Thanks?

Given a integer $n$, we assume we know all prime numbers between $n$ and $2n$. If we take randomlyWe call a prime number $p$, what is the probability thatp "good" if there exists a number $k$ stis $k<\log(p)$ and$0<k<logp$ with $2kp+1$ a prime number? Same question for $ k<\log^2(p)$. What is the asymptotic density of good primes.
