title: Display all prime number pairs whose sum is N
body: <p>I am working on a code for Goldbach Conjecture to display the prime number pairs whose sum is equal to a positive even number N. I was able to find these prime number pairs but I want to print all these prime number pairs equal to N in one single line.</p>
  <p>Any clue on how I would be able to work it out to achieve the desired result? This is the code I have worked out:</p>
  <pre><code>function goldB(N)
      for x = 6:2:N
          P = primes(x);
          for y = 1:length(primes(x))
              for z = 0:(length(P)-y)
                  if P(y) + P(y+z) == x
                      fprintf('\n%d = %d + %d',x,P(y),P(y+z));
                  end
              end
          end
      end
  end
  </code></pre>
