Formula to separate text from alpha numeric codes

Hi all,

I have a list of data that includes the "Training Subject" and the Training Code" in the same cell and I would like an easy to separate them - workbook attached

Sample:

Accessibility Training 81
Accountability Entry Control 78
Administration/Computers 31FP21
Advance Fire Prevention Inspections FPO502
Advance Fire Prevention Theory FPO501
Advanced Rope Rescue 74
Aerial Apparatus 20

Thanks
