Hello before4,

Not sure how 171 179 is coming as after 176 I couldn't see any thing continuous there. So if that is not the case then following may help you in same.
Code:
awk 'NR==1{Q=T=$0}NR>1{if(($0-Q)==1){q=0;} else {if(T==Q){T=$0;Q=$0;next};print T OFS Q;T=$0;Q=$0;next};Q=$0} END{print T OFS Q}' Input_file

Output will be as follows.
Code:
171 176
182 183
187 189
1900 1901
1903 1907

If above code doesn't help you or you have some other conditions in your requirement please get back to us with more precise Input_file and all the conditions and expected sample Output_file too.
EDIT: Changed code above a bit as it was no coming as per OP's expectation.

Thanks,
R. Singh
