A robot colors natural numbers starting from 1 in ascending order according to the following rule: any natural number that can be expressed as the sum of two composite numbers is colored red; those that do not meet this requirement are colored yellow. For example, 23 can be expressed as the sum of two composite numbers 15 and 8, so 23 is colored red, whereas 1 cannot be expressed as the sum of two composite numbers and is thus colored yellow. Determine the 1992nd number that is colored red when counted from the smallest in ascending order. Provide an explanation for your answer.
