- The technical gap involved in Goldbach's or the twin prime conjecture
- [or Schinzel's conjecture which is more important but less well known]
- is the parity problem in sieve methods. This is an extremely difficult
- and VERY important unsolved problem and involves some deep mathematics.
- Finding a way to solve the parity problem would settle MANY open problems.
- As such, it might be argued that it is a fundamental technique.
-
- The study of FLT is important not because one really cares about solutions
- of this particular equation, but rather because its study has led to the
- development of techniques that are applicable to MANY problems.

- Chen's method is fairly well known among analytic number theorists.
