Yes, can. For example, at first summarizes all numbers, except 2, 256 and 978 (499264 turns out), then multiplies 2, 256 and 978 (500736 turn out), and then puts two numbers and receives 1000000. Other example how to receive 1000000: to summarize all numbers, except 2 and 996 (499502 turn out), then to multiply on 2 (999004) and to add 996 (1000000).
