Determine all possible 7-digit decimal (base 10) perfect square(s), each of whose digits is nonzero and even.

Note: While a solution is trivial with the aid of a computer program, show how to derive it without one.

(In reply to re(2): SLOANE A103705 (spoiler) by Ady TZIDON)

I would bet Ady didn't mean to be rude, but the comment was kind of harsh.

Keep in mind that several of these solutions can be found online, but it's more gracious to just put the solution down and say how you found it.

In this case, since K asks for no computer solutions, you could say "If computer solutions were desired, I could find ___ with this program"
