404 x 58 = 23432. 927 x 68 = 63036.
In each case, the product of a 2-digit and a 3-digit integer is a 5-digit "wave" number. This is an integer whose digits rise (or fall) in an arithmetic progression from the beginning to the middle and then fall (or rise) in exactly the reverse manner to the end. So it turns out that they're all palindromes as well.
