We want to engrave the names of several distinguished professors on the wall of Amirkabir University. The name of each professor will be written on a tile $1 \times 1$. We intend to select a rectangle of size $a \times b$ on the wall with $a.b$ tiles and inscribe the professors' names on them.

The university will approve this request if the following conditions are met:

1. First, the names of $n$ faculty members of the Computer Engineering Department must be included in this tribute.
2. Second, the perimeter of this rectangle, that is, $2a + 2b$, must be minimized.
3. Third, the values of $a$ and $b$ must be prime numbers.

Given a natural number $n$, you are asked to calculate the minimum possible perimeter for this tribute.

The first line of input contains a positive integer $t$, representing the number of test cases.

$$1 \leq t \leq 100$$

In the next $t$ lines, each line contains an integer $n$, representing the number of professors for that test case.

$$1 \leq n \leq 10^9$$

خروجی

For each of the $t$ test cases, print a natural number representing the minimum required perimeter.
