In Traceroute source code why the destination port is assigned to 32678+666

u_short port = 32768 + 666; I don't know why they added 32768 with 666. Is there any meaning? where does 666 comes from? The range of the destination port is from 33434 to 33534. Why they haven't directly specify as 33434 (32768 + 666 = 33434)
