```cpp

flag=0;
}
}
return flag;
}
int main(){
long long n;
cin>>n;
for(int k=4;k<=n;k+=2){
for(long long i=2;i<=k/2;i++){
if(sushu(i)&&sushu(k-i)){
cout<<k<<"="<<i<<"+"<<k-i<<endl;
break;
}
}
}
return 0;

@[liyirong567](/user/955954) `if(bool(i)){`是`if(sushu(i))`啊……

@[蔡竣凯](/user/341036) 搞错了……刚刚发现之后直接A掉
