The number should be even numbers with two in the ten-thousand places.
Only the even digit number left is eight so the 8 should be the first place.
In the ten-thousand places, you should arrange the three digits in the middle. 3*2 = 6 ways so there are six ways to arrange the middle three digits in the ten-thousand places.
Answer: 23958, 23598, 25938, 25398, 29358, 29538
