If each letter has a value (a=1, b=2, c=3, d=4 etc.) what words containing at least four letters have the same total letter value as their antonyms (also containing at least four letters)? What is the longest such word with this property?

*** Plurals, proper nouns, hyphens, spaces, acronyms and abbreviations are not allowed.
