What It Is

Goldbach r(2n) --- number of unordered representations of 2n as p+q with both p,q prime. Highly erratic (Hardy-Littlewood: mean ~2*C_2*S(n)*2n/log^2(2n)) with strong primorial bias (r(2n) jumps when 2n is divisible by many small primes). Distinct mechanism from Divisor Count d(n): additive prime structure vs multiplicative divisor structure

Interpretation

Standard analysis sees: anti-correlated (alternating); blue spectrum (high-frequency power); strongly periodic; homoskedastic; monofractal. The atlas additionally detects Nonstationarity:adf_pvalue. It sits beside Stern-Brocot Walk in the atlas (standard-bank rank 132) — a neighbor conventional features miss.
