Compile a list of pairs of words beginning - one by pro , the other by con and sharing the same strings of letters as a second part of the word.

Examples:
Protest - contest, profess- confess, protractor-contractor, prostitution - constitution …etc

I have provided some examples, not to worry, there is a plentitude of qualifying pairs.

(In reply to An interesting answer by Math Man)

That was already given in the very first entry of my comment.
