Something like

procedure DO_SOME_DBMS_STATS(p number, maxparallel number) is begin
for i in (
  select * from (
    select mod(rownum,maxparallel ) r, segment_name, ...     from dba_segments
    order by bytes
  )
  where r = p ) loop
    dbms_stats.gather_table_stats(....)
end loop;
end;

for i in 0 .. maxparallel-1 loop
dbms_job.submit('DO_SOME_DBMS_STATS('||i||','||maxparallel||');') end loop;
