Complete my number sequence

Can you complete following number sequence ?

389919, 1308, 93, ?, ?

Hint:

mirror

$$389 + 919 = 1308$$, the number $$919$$ is mirrored, but is still the same. $$13 + 80 = 93$$, here $$08$$ gets mirrored. So you have to mirror the numbers second half and add it to the first half.
