- No. The twin prime conjecture is still open. The closest anyone has come
- is Chen's result on Goldbach's conjecture which says that all even
- integers are the sum of a prime and a number which is the product of at
- most two primes. This result can be extended to show that there exists
- an infinite number of primes p such that p+2 has a bounded number of
- prime factors.
-
- This conjecture is a special case of Schinzel's conjecture, which in
- turn is a special case of the Bateman-Horn conjecture. I discussed these
- conjectures just a couple of months ago. I am not going to repeat that stuff
- here.
-
- If you would like to see where the difficulty lies in obtaining proofs
- of these conjectures I would suggest you start with Halberstam & Richert's
- "Sieve Methods". A superb book IMO [but very difficult and somewhat terse].
