Erdős 11

Is every odd n>1n > 1 the sum of a squarefree number and a power of 2?

No one has attempted this yet.

Formal statement

Lean type

∀ (n : ℕ), Odd n → 1 < n → ∃ k l, Squarefree k ∧ n = k + 2 ^ l

Something wrong with this formalization?

A statement that does not faithfully capture the original conjecture is the one real risk here, so we would rather hear about it early - before someone spends weeks on it.
