Deleting cells that contain a specific number only from a space delimited text file

I have this space delimited large text file with more than 1,000,000+ columns and about 100 rows. I want to delete all the cells that consist of just 2 (leave 2's that are not by themselves intact):


File before modification
Code:
aa bb cc 2 NA100 dd
aa b1 c2 2 NA102 de

File after modification
Code:
aa bb cc NA100 dd
aa b1 c2 NA102 de

How would I delete all the cells that just have 2? Thanks!
