However, I am curious why you claim that pi x + y = e has no solution
in natural x and y, but that it is unknown whether pi x - y = e has a
solution. It would seem that one has a solution if and only if the
other does.

Natural number means positive integer, hence x >= 1.

OP, whom you snipped, allowed 0 as a natural number. Of course
even with that definition it's clear pi x + y = e has no solution in
natural x and y.

And, for the record, I prefer your convention to that of OP.

When I was in school, the whole numbers included 0 and the natural
numbers did not, so I am used to that definition, too.
