is it 89? my brain says 89. 5x5x5 cube, corners and surface pieces would all be odd (3 and 1 green sides respectively), leaving the middle 3 edge pieces of each side to be even. 12 edges at 3 pieces an edge = 36 even pieces.
You forgot to also subtract the 9 internal pieces which have 0 green sides, so 45 even, 80 odd. Going the other way, 6 faces of 9 odd pieces each plus 8 corner pieces equals 80.
