Exponential Equation
Description
You are given an integer $n$.
Find any pair of integers $(x,y)$ ($1\leq x,y\leq n$) such that $x^y\cdot y+y^x\cdot x = n$.
The first line contains a single integer $t$ ($1\leq t\leq 10^4$) — the number of test cases.
Each test case contains one line with a single integer $n$ ($1\leq n\leq 10^9$).
For each test case, if possible, print two integers $x$ and $y$ ($1\leq x,y\leq n$). If there are multiple answers, print any.
Otherwise, print $-1$.
Input
The first line contains a single integer $t$ ($1\leq t\leq 10^4$) — the number of test cases.
Each test case contains one line with a single integer $n$ ($1\leq n\leq 10^9$).
Output
For each test case, if possible, print two integers $x$ and $y$ ($1\leq x,y\leq n$). If there are multiple answers, print any.
Otherwise, print $-1$.

Note
In the third test case, $2^3 \cdot 3+3^2 \cdot 2 = 42$, so $(2,3),(3,2)$ will be considered as legal solutions.
In the fourth test case, $5^5 \cdot 5+5^5 \cdot 5 = 31250$, so $(5,5)$ is a legal solution.
