The Twin Prime Conjecture is a conjecture (i.e., not a theorem) that states that there are infinitely many pairs of twin primes, i.e. pairs of primes that differ by .

Failed Proofs
Using an infinite series
One possible strategy to prove the infinitude of twin primes is an idea adopted from the proof of Dirichlet's Theorem. If one can show that the sum
![$B=\frac{1}{3}+\frac{1}{5}+\frac{1}{5}+\frac{1}{7}+\frac{1}{11}+\frac{1}{13}+\frac{1}{17}+\frac{1}{19}+\cdots$](http://latex.artofproblemsolving.com/a/1/2/a12e076b39c41c67669c21ae7404809000ed1a6e.png)
of the reciprocals of twin primes diverges, this would imply that there are infinitely many twin primes. Unfortunately, it has been shown that this sum converges to a constant , known as Brun's constant. This could mean either that there are finitely many twin prime pairs or that they are spaced "too far apart" for that series to diverge.
Yitang Zhang approach
A weaker version of twin prime conjecture was proved by Yitang Zhang in 2013. This version stated that there are infinitely many pairs of primes that differ by a finite number. The number Yitang chose was 7,000,000. Terence Tao and other people have reduced that boundary to 246 more numbers.
Elementary proof
Some nerd called Zhangaik posted a solution here originally. It's wrong.
Alternative statements
One alternative statement of the Twin Prime Conjecture, is that there exists infinitely many natural numbers not of forms: with natural number inputs greater than 0. Because, letting
be of one of these forms one of
factors so only if one of variables is 0 will the factorization be trivial (contain only 1 and itself).
Another is that there are infinitely many values that have goldbach partitions of distance from
of 1.
