Harder than Wordle but still solvable. Mine:

  25943
   +- -
  65393
  ++--
  65839
  +++++

Some luck, but you can also lock in odd numbers before proceeding to add evens. And it obviously can't end in an even.

It's not a 5 digit prime.

0 is a digit.

Apparently I have stumbled over an idiom of the prime-enthusiast community.

97501 and 24683 will get you all of the numbers (and maybe some position matches), from there it becomes much easier.
