ArrayList递归不考虑重复元素

我有这段代码显示了达到目标数字的输出，例如目标= 1590，但它似乎并未考虑达到目标数字的3的倍数

import java.util.ArrayList;
import java.util.Arrays;

class SumSet {
    static void sum_up_recursive(ArrayList<Integer> numbers, int target, ArrayList<Integer> partial) {
       int s = 0;
       for (int x: partial) s += x;
       if (s == target)
            System.out.println("sum("+Arrays.toString(partial.toArray())+")="+target);
       if (s >= target)
            return;
       for(int i=0;i<numbers.size();i++) {
             ArrayList<Integer> remaining = new ArrayList<Integer>();
             int n = numbers.get(i);
             for (int j=i+1; j<numbers.size();j++) remaining.add(numbers.get(j));
             ArrayList<Integer> partial_rec = new ArrayList<Integer>(partial);
             partial_rec.add(n);
             sum_up_recursive(remaining,target,partial_rec);
       }
    }
    static void sum_up(ArrayList<Integer> numbers, int target) {
        sum_up_recursive(numbers,target,new ArrayList<Integer>());
    }
    public static void main(String args[]) {
        Integer[] numbers = {431, 431, 429, 427, 424, 422, 420, 418, 416, 414, 412,
    409, 407, 405, 403, 401, 398, 396, 394, 392, 389, 409, 347, 347, 344, 344, 342, 342,
    339, 342, 344, 347, 349, 352, 354, 357, 359, 361, 364, 364, 364, 364, 431, 451, 449, 447,
    445, 443, 441, 439, 437, 435, 433, 431, 429, 427, 424, 422, 420, 418, 416, 414, 412};
        int target = 1590;
        sum_up(new ArrayList<Integer>(Arrays.asList(numbers)),target);
    }
}

对于示例输出，sum（[431，424，396，339]）= 1590，但它不像这些[424，392，392，392]也占3x组合也= 1590

我将如何重新计算元素以达到目标数量？
