Sort multiple files from one folder based on prefix and timestamp

There is multiple 500+ files in one folder. All of files has same filename structure.
Example: 15-01_Decin_15-01_Decin_main_20220516053118.jpg
Prefix: 15-01_Decin
Timestamp: 20220516053118 (YYYYMMDDHHMMSS)

This file I need to move to folder 20220516(YYYYMMDD), which is subfolder of folder 15-01_Decin (prefix).
If niether folder or subfolder does not exist, they need to be created.

Example of filenames with different prefix.

I do prefer a solution with a windows CMD batch.
