   Golbach conjecture
  Golbdach is so simple to define, and so hard to demonstrate... My feeling is that it will elude ZFC. Prime numbers are elementary bricks among natural numbers. N and P have the same size. Goldbach is another way to define ONE of the ZFC axioms.In other words, we are chasing in vain : it is true, but undemonstrable.
