8.4. There are two types of five-digit numbers as follows:
(1) The sum of the digits is 36, and it is an even number;
(2) The sum of the digits is 38, and it is an odd number.

Try to determine: which type of number is more? Explain your reasoning.
8.4. It is easy to see that the digits of a five-digit number whose sum of digits equals 38 cannot include 0, otherwise its sum of digits would not exceed \(4 \times 9 = 36\). If we subtract 1 from each of the last two digits of each odd number whose sum of digits equals 38, we can obtain an even number whose sum of digits equals 36. Different odd numbers yield different even numbers, so the number of odd numbers whose sum of digits equals 38 is no more than the number of even numbers whose sum of digits equals 36. On the other hand, there exist even five-digit numbers whose sum of digits equals 36 (such as 99 990) that cannot be obtained through this method. Therefore, there are more even numbers whose sum of digits equals 36.
