题目描述

You are given a positive integer $n$ . You have to find $4$ positive integers $a, b, c, d$ such that

- $a + b + c + d = n$ , and
- $\gcd(a, b) = \operatorname{lcm}(c, d)$ .

If there are several possible answers you can output any of them. It is possible to show that the answer always exists.

In this problem $\gcd(a, b)$ denotes the [greatest common divisor](https://en.wikipedia.org/wiki/Greatest_common_divisor) of $a$ and $b$ , and $\operatorname{lcm}(c, d)$ denotes the [least common multiple](https://en.wikipedia.org/wiki/Least_common_multiple) of $c$ and $d$ .

输入格式

The input consists of multiple test cases. The first line contains a single integer $t$ ( $1 \le t \le 10^4$ ) — the number of test cases. Description of the test cases follows.

Each test case contains a single line with integer $n$ ( $4 \le n \le 10^9$ ) — the sum of $a$ , $b$ , $c$ , and $d$ .

输出格式

For each test case output $4$ positive integers $a$ , $b$ , $c$ , $d$ such that $a + b + c + d = n$ and $\gcd(a, b) = \operatorname{lcm}(c, d)$ .
