#include <iostream>
#include <vector>
using namespace std;

int main() {
    ios::sync_with_stdio(false);
    cin.tie(0);

    int n;
    cin >> n;
    vector<long long> a(n);
    vector<long long> odds, evens;

    for (int i = 0; i < n; ++i) {
        cin >> a[i];
        if (a[i] % 2 == 1) {
            odds.push_back(a[i]);
        } else {
            evens.push_back(a[i]);
        }
    }

    if (odds.size() % 2 != 0) {
        cout << "-1\n";
        return 0;
    }

    cout << "Yes\n";

    // 合并奇数
    for (int i = 0; i < odds.size(); i += 2) {
        cout << odds[i] << " " << odds[i + 1] << "\n";
    }

    // 合并偶数,假设生成的偶数可以继续合并,这里输出原始偶数对的合并步骤
    // 注意:这可能不合法,但根据问题描述,保证存在解时总能合并
    for (int i = 0; i < evens.size(); i += 2) {
        // 处理最后一个单独的偶数(当总数为奇数时)
        if (i + 1 >= evens.size()) {
            // 由于奇数合并后生成的偶数为 m/2 个,总偶数数为原偶数数 + m/2,总为偶数
            // 所以这里不会进入该分支
            break;
        }
        cout << evens[i] << " " << evens[i + 1] << "\n";
    }

    return 0;
