this term is already in the b-file,
http://www.research.att.com/~njas/sequences/b055153.txt
(as is the other term in A141645)

It is also e.g. on
http://home.att.net/~numericana/answer/numbers.htm
as can be found via
http://www.google.com/search?q=228350830852095014942603539620449439316967424

afaik, the major difficulty is not to find such terms
but to be sure that there are no smaller ones missing in the list.
