Erdős Problem #869 — If $A_1,A_2$ are disjoint additive bases of order $2$ (i.

If $A_1,A_2$ are disjoint additive bases of order $2$ (i.e. $A_i+A_i$ contains all large integers) then must $A=A_1\cup A_2$ contain a minimal additive basis of order $2$ (one such that deleting any element creates infinitely many $n ot\in A+A$)?
