停顿几秒钟执行

<script>
       let i = 0;
       let time = null;
       clearInterval(time);
       time= setInterval(fun, 2000);
    function fun(){
        i++;
        if(i%2==0){
            clearInterval(time);
            setTimeout(() => {
                console.log("偶数",666)
                time= setInterval(fun, 2000);
            },2000);
        }
        console.log("打印！！",i)
    }
