I happened to see this problem. So I came up with a similar problem below.

How many integers \(n>1\) are there such that \(n,n+2,n+6\) are all prime numbers ?

If there are infinitely many such n, then the twin prime conjecture is true. I suggest working on the twin prime conjecture first, because it is (likely) easier.Log in to reply

Has anyone come close to proving the twin prime conjecture or do we need to solve the Riemann hypothesis first?Log in to reply

Here is a good introductory read to the relationships between TP and RH. It is written by Dan Goldston (same as the above), though prior to Zhang's discovery. If you can understand through the first 5 chapters, that would be great

Yes, even as I was working out I found many numbers,

Here's my explanation,

I didn't know 71+6=79. :PLog in to reply

@Sravanth Chebrolu I think you must develop a habit of always cross checking your work. :) – Nihar Mahajan · 1 year, 9 months ago
