ran.pasteHTML('<span style="font-size:20px;">example</span>');

pasteHTML will delete the current selection from the document, so I assume you want to select the span you've replaced it with. To do this, add an ID to the span, move the TextRange to encompass its text and select it, as follows:

var ran = Editor.selection.createRange();
ran.pasteHTML('<span style="font-size:20px;" id="a_random_unique_id">example</span>');

var spanRange = ran.duplicate();
spanRange.moveToElementText( document.getElementById("a_random_unique_id") );
spanRange.select();
