Proof step 4 from proof primes-max-even (previous step)

∀ i. i ∈ ints → prime(i) ⊦ ints = [], even(max(ints)) ↔ max(ints) = 2

Heuristic quantifier applied rule all left

And obtained the following new goals

Proof step 5:
4 ∈ ints → prime(4), ∀ i. i ∈ ints → prime(i) ⊦ ints = [], even(max(ints)) ↔ max(ints) = 2
