Proof step 29 from proof int2bytes-len-neg (previous step)

j = 0 - 2 ^ (8 * i), j < 0, 2 ^ (8 * i) ≤ 2 ^ (8 * (i + 1) - 1), 0 ≤ i, 0 ≤ 2 ^ (8 * (i + 1) - 1) + j ⊦ # int2bits(j) / 8 = i→n(i), # int2bits(j) % 8 = 0

User applied rule insert equation

And obtained the following new goals

Proof step 30:
0 - 2 ^ (8 * i) < 0, 2 ^ (8 * i) ≤ 2 ^ (8 * (i + 1) - 1), 0 ≤ i, 0 ≤ 2 ^ (8 * (i + 1) - 1) + (0 - 2 ^ (8 * i)) ⊦ # int2bits(0 - 2 ^ (8 * i)) / 8 = i→n(i), # int2bits(0 - 2 ^ (8 * i)) % 8 = 0
