The smallest 4-digit palindrome is 1001. To find if it can be expressed as the sum of two 3-digit palindromes, consider the smallest 3-digit palindromes, which are 101, 111, 121, etc. The combination of 101 and 900 (another 3-digit palindrome) gives 1001, making 1001 the sum of two 3-digit palindromes. Thus, the answer is 1001.
The smallest digit palindrome that is the sum of two 3-digit palindromes is 121. This is achieved by adding the two 3-digit palindromes 101 and 20, both of which are palindromic. Therefore, 101 + 101 = 202, but if we consider a valid case with two different palindromes, we can use 111 and 110, which gives us 221, the next smallest palindrome. However, the smallest individual palindrome formed by the sum of any two 3-digit palindromes remains 121.
Largest three digit number is 999 and we see that it is odd. One less than that is 998 and it is even and it is also three digits. No other 3 digit number is larger than 998 while being even.
906609=913*993 I found this using a relatively simple computer program that I wrote.

To find the largest three-digit even number using the digits 3, 4, and 5, you need to arrange these digits in descending order to maximize the number, ensuring that the last digit is even. The largest possible even number is 542
