Chapter 213: What to Do with a Mathematics Master Sitting Downstairs?

Twin primes refers to pairs of prime numbers that differ by 2, such as 3 and 5, 5 and 7, 11 and 13, and so on.

The Twin Prime Conjecture, proposed by Hilbert in his report at the 1900 International Congress of Mathematicians, can be described as follows--

There are infinitely many prime numbers p, such that p + 2 is also a prime number.

The prime pairs (p, p + 2) are referred to as twin primes.

Since this conjecture was raised, it has become one of the world's mathematical puzzles and one of the classic number theory conjectures.

Over the past century, countless mathematicians have conducted research on the Twin Prime Conjecture, providing many proof strategies, one of which is a weaker version of the Twin Prime Conjecture, "find a positive number so that there are infinitely many pairs of primes the difference of which is less than this given positive number." In the Twin Prime Conjecture, this positive number is 2.
