One less formal way of looking at it is this: there are an infinite number of multiples of 35. starting with 35, 70, 105. Add 6 to each of the odd multiples. 35+6=41 (prime); 105+6 = 111 (prime). With an infinite # of candidates, you’ve gotta get to an infinite number of solutions (for some value of infinity!)
As for that Dirichlet stuff, it’s way beyond any of the useful stuff I learned too.
No, I wouldn’t assume non-convergence either … NOR would I assume that that AI didn’t just grab that ‘high-level’ ‘Elaboration’ from some site … without a citation.
