You might try adding it to the meta description (assuming you have one), close enough to phrases likely to be searched that it will get displayed.

This isn't as prominent as the title nor as certain to be returned, but it's less likely to change ranking position. You could then track "solved" pages for a while, to see if that affects click-through. If it does, then perhaps risk it on some titles (and first try it on lesser pages before rolling it out sitewide).

IMO, adding a word to the beginning of a title is taking a risk. Google is a machine, and we can't assume it could connect all the dots a human could in interpreting the word.
