If anyone could help me out with this I would apreciate this:

Is it possible to find/make an algorithm to find out the best possible sum
to make a specified large number?


Here is a typical number I have to deal with - 169041087053108217.
I need to break this down into 3 or 4 separate numbers that will get me back
to the original number.

n * x * y * z = largenumber or
x * x + z = largenumber or
x + y * z - n = largenumber

you get the idea.

Each of these smaller numbers pref needs to be 255 or less (but under 65535
will do).

Any help would be appreciated! (please mail me on ben at
