有点烦 有些地方 都不知道为什么错

```def f(n):
    for i in range(2,int(n**0.5+1)):
        if n%i==0:
            return False
    return True
      


while True:
    try:
        n=int(input())
        for i in range(int(n/2)):
            k=n/2 -i
            l=n/2+i
            
            if f(k) and f(l):
                print(int(k))
                print(int(l))
                break
                break
