Sequence of lists

Let's say I have the following table, y=40; b=Flatten[Table[{i, j}, {i, 1, 2.25, 1.25}, {j, y - 5, y - 8, -3}], 1] then c is equal to, c = b - ConstantArray[{0, 8}, 4] and the out put is {{1., 27}, { … again, y is >=4, which is fine, and f equal to f = e - ConstantArray[{0, 8}, 4] the output is {{1., 3}, {1., 0}, {2.25, 3}, {2.25, 0}} so now in f, y less than 4, so it is not fine, How can I make a table
