Two more:

$2a$04$112345678911234567891ur.oaCV2tDJHauGmoz3XARSRocAbQ0Ci:21542
$2a$04$112345678911234567891uVnXpBKo1PxsBoYbrgOLkoMFF1zhBEeG:39883

These are 6 and 11 (mod 32).

So far all three have this in common: the second one of two salts, and
the (mod 32) password numbers are all within the first half of a
32-password range.  (When generating these hashes, one of the two salts
was chosen at random, without obvious correlation to hash number.  So
these are two separate observations.)

Of course, 3 is not enough for statistics.
