Interesting math problem! Finding those integers involves some cube calculations. I might even build a Snow Rider game level around it, where players collect digits that add up to the original number! Perhaps a Python script could help automate the search. I suspect there are relatively few satisfying both conditions. Anyone found a prime number yet?
