You can override getValue() function in this js in your module

vendor/magento/module-tax/view/frontend/web/js/view/checkout/summary/subtotal.js

In your custom module you can override that function as below...

app/code/MageHelper/ShippingDiscount/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'MageHelper_ShippingDiscount',
    __DIR__
);

app/code/MageHelper/ShippingDiscount/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="MageHelper_ShippingDiscount" setup_version="1.0.0" />
</config>

app/code/MageHelper/ShippingDiscount/view/frontend/requirejs-config.js

var config = {
    config: {
        mixins: {
            'Magento_Tax/js/view/checkout/summary/subtotal': {
                'MageHelper_ShippingDiscount/js/view/checkout/summary/subtotal-mixin': true
            }
        }
    }
};

app/code/MageHelper/ShippingDiscount/view/frontend/web/js/view/checkout/summary/subtotal-mixin.js

define([
    'Magento_Checkout/js/view/summary/abstract-total',
    'Magento_Checkout/js/model/quote'
], function (Component, quote) {
    'use strict';

    var mixin = {
        getValue: function () {
            var price = 0;

            if (this.totals()) {
                price = this.totals().subtotal + this.totals().base_discount_amount;
            }

            return this.getFormattedPrice(price);
        }
    };

    return function (target) {
        return target.extend(mixin);
    };
});

You can add your vendor and module name where I've added MageHelper and ShippingDiscount

Hope this will work for you.
