Splitting a file more than 30 GB size with specific condition

I have a file name "xzy.dat". It is of size more than 30 GB.

The content of file would be something like this

12345678 244466 2017101820171021 00077898 00011111 00022222

Above record is a bad record. A normal record would look something like this

12345678A244466 2017101820171021 00077898 00011111 00022222

If u observe, there's an alphabbet "A"(or any other character) missing from the first example line that i provided at 9th Position. That's clearly wrong. Instead there's a space in that line.

I want to split my 30 GB file in two files in such a way that any string which has a space in that position (9th Position) should be moved to a different file and rest of the good records to another file.

Can this be done? If yes, can you please guide me to do so.


Thank You,
Vikram
