how to set mask

hi,all
i got a half md5 hash value,and i am sure the password contain some number parts,how to use mask;

hash value E3DC86917650198B
password contain 4 parts: 200002        2018053019184400        100       426
maybe contain the 5th part ,but i dont know what it is 
and the order of that 4 parts is unknow,password length is also unknow.

eg.
halfMd5(200002 + 5th part + 2018053019184400+100+426)  = E3DC86917650198B
halfMd5(200002 + 2018053019184400 + 5th part +100+426)  = E3DC86917650198B
