Problem: One way to create a task is to learn from math. You can generate some random math statement or modify some theorems to get something new and build a new task from that.

For example, there is a statement called the "Goldbach's conjecture". It says: "each even number no less than four can be expressed as the sum of two primes". Let's modify it. How about a statement like that: "each integer no less than 12 can be expressed as the sum of two composite numbers." Not like the Goldbach's conjecture, I can prove this theorem.

You are given an integer n no less than 12, express it as a sum of two composite numbers.

Input

The only line contains an integer n (12 ≤ n ≤ 106).

Output

Output two composite integers x and y (1 < x, y < n) such that x + y = n. If there are multiple solutions, you can output any of them.

Examples

Input

12


Output

4 8


Input

15


Output

6 9


Input

23


Output

8 15


Input

1000000


Output

500000 500000

Note

In the first example, 12 = 4 + 8 and both 4, 8 are composite numbers. You can output "6 6" or "8 4" as well.

In the second example, 15 = 6 + 9. Note that you can't output "1 14" because 1 is not a composite number.

Solution (in PYTHON3):

Solution:
import math
n=int(input())
def checkComposite(n):
    t=bool
    if n%2==0 or n%3==0:
        t=True
    else:
        i=5
        while (i*i <= n):
            if (n%i==0  or n%(i+2)==0):
                t=True
                break
            i+=6
        t=False
    return(t)

v1=math.ceil(n/2)
rm=n-v1
if(v1==rm):
    v1-=1
    rm+=1
    while(not(checkComposite(v1) and checkComposite(rm))):
        v1=v1-1
        rm=rm+1
    print(v1,rm)
else:
    while(not(checkComposite(v1) and checkComposite(rm))):
        v1=v1-1
        rm=rm+1
    print(v1,rm)
