Сколько среди чисел от 5584 до 6654 (включительно) таких чисел, для которых выполняются одновременно два свойства: они простые их сумма цифр четна

Вc++ #include < iostream> int main(){ using namespace std; int k = 0;     //счетчик чисел for (int i = 5584; i < = 6654; i++) { int issimple = 1; for (int j = 2; j < i / 2; j++) if (i % j == 0) { issimple = 0;   //значит, число составное break; } if (issimple ! = 0) { int j = i; int sumnum = 0; while (j > 0) { sumnum = sumnum + (j % 10);     //находим сумму цифр числа j = j / 10; } if (sumnum % 2 == 0) k = k + 1; } } cout < < k < < endl; return 0; }
