You can do it using preference tag.

inside app/etc/di.xml file,

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

<preference for="Magento\Sales\Block\Adminhtml\Invoice" type="Package\ModuleName\Block\Adminhtml\Invoice" />  


You can create invoice.php file inside Package\ModuleName\Block\Adminhtml folder and changes core data.
