How to Pose the Mathematical Problem of the Goldbach's Strong Conjecture ? A New Idea for a New Solution

The aim of this short paper is to define the real mathematical problem of Goldbach's strong conjecture (GSC), which remains officially unsolved. It attempts to propose a method based on the analysis of remainders of Euclidean division to explain why two equidistant primes add up to an even number. Let's not forget that in mathematics, posing the problem correctly is the surest way to the solution.
