Hey, I'm trying to figure out how to figure this out. (lol)

Basically, I have a number, 22040, there is a matching number for it that I am trying to figure out.

For example, I know 14100's matching number is 10674, and 12819's matching number is 15503, 6472's matching number is 12281.

What's the connection, can anyone see it? I can't...

Kind Regards
Icyculyr
