(still editing...)\\ For each sufficiently large prime $p$ of the form $4k+1$, we shall find a corresponding $n$ satisfying the required condition with the prime number in question being $p$. Since there exist infinitely many such primes and, for each of them, $n \ge \sqrt(p-1)$, we will have found infinitely many distinct $n$ satisfying the problem.
