perplexus.info :: Numbers : Increase or decrease by one

Increase or decrease by one (Posted on 2014-04-22)

The false equation :
5125*466=3327287
would become true, once each of its 14 digits
were either increased or decreased by 1.

What is the correct equation?

Rem: Analytical solution preferred.
