If your specific mention of a text file was arbitrary, you might consider Storable, which easily and efficiently stores a data structure for reuse at a later time. The downside is that the file isn't human readable. 

perl -e 'split//,q{john hurl, pest caretaker}and(map{print @_[$_]}(joi
+n(q{},map{sprintf(qq{%010u},$_)}(2**2*307*4993,5*101*641*5261,7*59*79
+*36997,13*17*71*45131,3**2*67*89*167*181))=~/\d{2}/g));'
