**Steve**, Tuesday, December 11, 2012 at 5:03amall you have to do is come up with 1 such number, then shuffle the digits around, leaving the last (even) digit alone.

6152438

now shuffle the digits, leaving 8 where it is. There are 6! = 720 ways to do it.

It was easy to come up with, since 29-8=21, so I just picked 3 pairs of digits that add up to 7, and stuck 'em in front of the 8.

**Eric**, Tuesday, December 11, 2012 at 9:48amThank you for your response. But, I just don't understand what you wrote. It seems completely different than what the question is asking. Because the statement says all 7 numbers are even?
