Even though I meant to put an end to this blog publishing a purposed proof of the asymptotic Goldbach conjecture, I finally decided, after the attack that took place in Paris yesterday, to keep on writing new articles here. This is my way to support Charlie Hebdo.
So, I observed that the upper bound would follow from both the inequality
established in the previous article and the relation
that came to my mind rather unexpectedly.
Maybe using once again the inequality of arithmetic and geometric means could help establish the latter rigorously.
