What makes it different fron Goldbach's conjecture?
I think a better example might be Goodstein's theorem [1].

The only drawback is that the theorem is somewhat more complicated
than Goldbach's conjecture -- not a lot, but a bit.

I am establishing a new meaning for
{true on the basis of meaning expressed in language}
Formerly known as {analytic truth}.
This makes True(L,x) computable and definable.
You may say that, but you then refuse to do the work to actually do that.

L is the language of a formal mathematical system.
x is an expression of that language.

When we understand that True(L,x) means that there is a finite
sequence of truth preserving operations in L from the semantic
meaning of x to x in L, then mathematical incompleteness is abolished.
Except you just defined that this isn't true, as you admit that the Goldbach conjecgture COULD be an analytic truth even if it doesn't have a finte sequence of truth perserving operations,
I redefined analytic truth to account for that. Things
like the Goldbach conjecture are in the different class
of currently unknowable.
Note, Godel's G can't be put into that category, as it is KNOWN to be true in PA, because of a proof in MM
