   5# Goldbach Conjecture from RS — C1 Mathematics
   6
   7The Goldbach conjecture (unproved) states every even number > 2 is
   8a sum of two primes.
   9
  10RS structural observation: prime sums correspond to J-cost pairings
  11where J(p_1/p_2) minimises over prime pairs.
  12
  13This module formalises the RS structural opening:
  141. Primes are recognition-cost minima on the integer lattice
  152. Goldbach = existence of two primes summing to n with equal/opposite cost
  163. The RS J-cost framework provides a structural explanation
  17
  18Not a proof of Goldbach — that requires Zhang-Maynard + Chen axioms.
  19This is the structural opening at the RS level.
