## 题目描述

<!-- description:start -->

<p>You are given two integers <code>n</code> and <code>m</code>.</p>
<p>给定两个整数&nbsp;<code>n</code> 和&nbsp;<code>m</code></p>

<p>You have to select a multiset of <strong><span data-keyword="prime-number">prime numbers</span></strong> from the <strong>first</strong> <code>m</code> prime numbers such that the sum of the selected primes is <strong>exactly</strong> <code>n</code>. You may use each prime number <strong>multiple</strong> times.</p>
<p>你必须从 <strong>前</strong> <code>m</code> 个 <strong><span data-keyword="prime-number">质数</span></strong> 中选择一个多重集合,使得所选质数的和 <strong>恰好</strong> 为 <code>n</code>。你可以 <strong>多次</strong> 使用每个质数。</p>

<p>Return the <strong>minimum</strong> number of prime numbers needed to sum up to <code>n</code>, or -1 if it is not possible.</p>
<p>返回组成 <code>n</code> 所需的最小质数个数,如果不可能,则返回 -1</p>
