If "a" minimal path is wanted (and not all) it sort of looks the same :) 

#!/usr/bin/perl

use strict; # https://perlmonks.org/?node_id=11128406
use warnings;
use List::Util qw( reduce );

local $_ = <<END;
            1
           2 4
          6 4 9
         5 1 7 2
END
my @d = map [ split ], split /\n/;

my %cache;

print path(0, 0), "\n";

sub path
  {
  my ($r, $c) = @_;
  $cache{"@_"} //= $r < $#d
    ? $d[$r][$c] . ' + ' .  reduce { eval $a <= eval $b ? $a : $b }
      path($r+1, $c), path($r+1, $c+1)
    : $d[$r][$c]
  }
