Q: Largest integer interval such that for all primes $p \in I$, we have that $p = 2 \pmod q$ for some $q \in Q$ a fixed finite set of primes?

MathCrackExchangeGiven a finite set of prime numbers $Q = \{ q_1, \dots, q_n\}$. What is the maximum size of any integer interval $I$ of consecutive integers such that for all $p \in I \cap \Bbb{P}$, $p =2 \pmod {q_i}$ for some $q_i \in Q$? This relates to the twin prime conjecture obviously.

delete Duplicate (which is also a very basic question) with an accepted answer.
