My quick hack
#!perl -l
$_=~('(.)'x5) && # (put our digits in $1..$5)
y/2357//==2 && # It has 2 prime digits.
"$1$2$4$5"!~/[$3-9]/ && # Digit 3 is the highest number.
"$1$3$4$5"!~/[0-$2]/ && # Digit 2 is lowest.
($5>$2&$5<$1|$5>$1&$5<$2) && # Digit 5 is between digit 2 and digit 1
$5==$4/2 && # ... and is half of digit 4.
!/(.).*\1/ && # There are no duplicates.
$1==$3-1 && # Digit 1 is 1 less than digit 3.
$1>$4+$5 && # Digit 1 is higher than the sum of digit
+s 4 and 5.
print for 0..9x5

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
