The first step of glucose breakdown is glycolysis in which there is a net gain of 8 ATP ( 6 ATP from NADH2 and 2 ATP by direct conversion from ADP) from 1 molecule of glucose.
However, 2 ATP are consumed and 4 ATP are produced by direct conversion per molecule of glucose during glycolysis. Hence, for 2 molecules of glucose, 4 ATP and 8 ATP are used and produced respectively in total.
So the answer is '4 and 8'.
