A book has 2020 pages. If the page number on a certain page can be composed of 2 or more consecutive natural numbers, then this page is called a "consecutive page." For example, the page numbers "21," "213," "1324," "9789," and "109" can be composed of "2, 1," "1, 2, 3," "1, 2, 3, 4," "97, 98," and "9, 10" respectively. Therefore, "21," "213," "1324," "9789," and "109" are examples of consecutive pages. However, "22," "217," and "122" are not consecutive pages. How many consecutive pages are there in this book?
