If you choose to revise this more, try to avoid using these phrases and instead show the connections that you imply with them. It may work to your advantage when communicating it.

Seems like you proved it by first assuming its true, then stating it was true. Doesn't quite work out to be a proof at that point.

I would pay - probably like \$5 - to see a proof of that.

I would say proof/disproof would revolve around the existence of a maximum distance an an arbitrary integer and it's closest perfect cube. Is there anything known about that?
