Apr 9, 2019 at 17:03 comment added Gerhard Paseman As an illustrative example, pick n=200. 21 pairs are mostly determined by the primes in (100,200). For the primes 71 and 73 you need two new pairs. By the time you reach 61 you have run out of options. Gerhard "Waves Hands For Larger Numbers" Paseman, 2019.04.09.
