Canonical assertion
The drafted Formal Conjectures statement for Erdős problem 435 (statements/435/435.lean) faithfully represents the boxed problem; machine verdict on the linked hosted proof: unconditional (plby).
Notation is rendered from the stored source. The pinned checkout remains the exact record.

Scope and conditions
theoretical
'What is the largest integer not of the form ...' rendered as `IsGreatest {m : Z | not exists c, m = sum ...} target`; both hosted theorems state `target n not-in Representable n && forall x : Z, x > target n -> x in Representable n`. Logically equivalent: membership plus the contrapositive of the upper-bound half of IsGreatest. IsGreatest is the idiomatic Mathlib packaging.; R
