Semi-Prime Number Definition
An integer greater than one is called a semi-prime number if it can be
decompounded to TWO prime numbers. For example, 6 is a semi-prime number
but 12 is not.
Your task is just to determinate whether a given number is a semi-prime number.
Input
There are several test cases in the input. Each case contains a single integer N (2 <= N <= 1,000,000)
Output
One line with a single integer for each case. If the number is a semi-prime number, then output "Yes", otherwise "No".
Sample Input
3 4 6 12
Sample Output
