How do Slice a string into pairs

For the project I am doing, I need to make pairs out of the input, but I can't figure out how, I could use some help.
How it is: 

2209222717080109

How I want it to become: 

["22","09","22","27","17","08","01","09"]

Convert it to a string, convert that into an array of characters, then take each consecutive slice of two characters, and join each of those slices together:

2209222717080109.to_s.chars.each_slice(2).map(&:join)
#=> ["22", "09", "22", "27", "17", "08", "01", "09"]

input = "2209222717080109"
input.chars.each_slice(2).map(&:join)
["22", "09", "22", "27", "17", "08", "01", "09"]
