Let

R(N)=∑m=0NΛ(m)Λ(N−m).R(N)=\sum_{m=0}^{N}\Lambda(m)\Lambda(N-m).R(N)=m=0∑N​Λ(m)Λ(N−m).

If

R(N)>2⌊N⌋(log⁡N)2,R(N)>2\lfloor\sqrt N\rfloor(\log N)^2,R(N)>2⌊N​⌋(logN)2,

then N is the sum of two primes. This improves the earlier extraction criterion by removing its extra floor(log₂ N) factor.

The proof uses the refined weighted proper-prime-power bound. If no prime pair exists, every term of the full convolution is a bad-pair term, so the full sum is at most the stated contamination bound. This contradicts the strict hypothesis. The finite sum includes both endpoints, and the argument applies to every natural N without an omitted small-number case.

The submitted source includes the complete weighted-contamination proof and imports no open platform theorem. This establishes a sufficient condition; it does not establish that condition for every large even number. Strong Goldbach and its uniform binary-correlation input remain unresolved.
