can someone tell me whats wrong with my code

i want to get the twin primes for the number 500 that is between 10 and 500 and the numbers has differnce by 2 like (17 19) i wrote this code but it seems there's somthing wrong and i can't get it

    x = primes(500);

    for i = 1:length(x)
    while (x(i)>10) && (x(i)<500)

        if (x(i+1) - x(i))= 2
            disp (x)
        end

    end

end

if (x(i+1) - x(i))= 2 is an error, use:

if x(i+1) - x(i)== 2

Also, use only the while loop

Try it this way:

x = primes(500)
for i = 1:length(x)-1
  if x(i) <= 10
    continue;
  end
  if (x(i+1) - x(i)) == 2
    fprintf('%d and %d\n', x(i), x(i+1));
  end  
end

Note that I got rid of the while loop you had, otherwise you have an infinite loop.
