We don't know that. Fermat's Last Theorem had a short cut, but it took 358 years to find it. At that rate, we won't find Goldbach's short cut (if it has one) for another 75 years.

Only if it's true. So if it's true, the testing program will never halt. But if it's false, the tester will eventually find the counter- example, print it, and stop.

So a program that can tell whether another program will halt can tell us whether Goldbach's conjecture is true.

It would be the short cut that you say doesn't exist.

I am refuting the key halting problem
You mean the proof when you admitted *multiple time* that the theorem is proves is correct?
