Problem Description

Chinese mathematician Chen Jingrun made significant breakthroughs in proving the Goldbach Conjecture.

He demonstrated that "every sufficiently large even number (greater than $10$) can be expressed as a prime number plus the product of two prime numbers," known as the $1+2$ problem:

12 = 3 + 3 * 3  
14 = 5 + 3 * 3  
16 = 7 + 3 * 3  
18 = 3 + 3 * 5  
20 = 5 + 3 * 5  

Input Format

The input consists of a single line containing an even number $N$ greater than $10$.

Output Format

The output should be a single line displaying the required expression.

This problem uses Special Judge, meaning any valid answer will be accepted. Note that in your output $N=a+b\times c$, the following conditions must be satisfied: $1\le a,b,c\le n$ and $a,b,c$ must be prime numbers.

Samples

12

12=3+3*3

14

Data Range

For $100\%$ of the test cases, $12 \le n \le 10^6$ and $n$ is an even number.
