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:
def isComposite(n): 
    if (n <= 1): return False
    if (n <= 3): return False

    if (n % 2 == 0 or n % 3 == 0): return True
    
    i = 5
    while(i * i <= n): 
        if (n % i == 0 or n % (i + 2) == 0): return True
        i = i + 6
    return False

number = int(input())
smallestComposite = 4

rngNumbers = list(range(smallestComposite,number+1-smallestComposite))
foundTheAnswer = False

while(foundTheAnswer is not True):
  num = rngNumbers[0]
  #print(rngNumbers)
  if(isComposite(num)):
    #print(str(num) + " is composite")
    if(isComposite(rngNumbers[len(rngNumbers)-1])):
      #print(str(rngNumbers[len(rngNumbers)-1]) + " is composite")
      print(num, rngNumbers[len(rngNumbers)-1])
      foundTheAnswer = True
    else:
      #print(str(rngNumbers[len(rngNumbers)-1]) + " is NOT composite")
      rngNumbers.remove(rngNumbers[len(rngNumbers)-1])
      rngNumbers.remove(num)
  else:
    #print(str(num) + " is NOT composite")
    rngNumbers.remove(rngNumbers[len(rngNumbers)-1])
    rngNumbers.remove(num)
