The article for the Goldbach conjecture links two Helfgott papers. I think if we ask Helfgott himself, he'd be quite happy to have just the links to his papers, and not a link to a Wikipedia page which could potentially be used to spread lies about him.

Looking through the article history, maybe you are asking the question ? If so, using this link 1, what is computes seems to match your estimates:
- n=1000 gave 28 vs "expected" 25
- n=990 gave 52 vs "expected" 52
So it seems the issue is comparing expected to A002375 /2n.
