Proof step 5 from proof prime-odd (previous step)

j % 2 = 0, 0 < j, prime(j) ⊦ j = 2

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
j % 2 = 0, 0 < j, prime(j) ⊦ j = 2

Rule argument

Additional information

Used simplifier rules: forward-le-05: ⊦ i < j ∧ 0 ≤ i → 0 < j; (forward) from specification int-abs
