29 = 225 - 196
28 = 64 - 36
27 = 36 - 9
25 = 169 - 144
24 = 25 - 1
23 = 144 - 121
21 = 25 - 4
20 = 36 - 16
19 = 100 - 81
17 = 81 - 64
16 = 25 - 9
15 = 16 - 1
13 = 49 - 36
12 = 16 - 4
11 = 36 - 25
9 = 25 - 16
8 = 9 - 1
7 = 16 - 9
5 = 9 - 4
3 = 4 - 1
1 = 1 - 0 (if you include zero as a square number)
0 = any square number subtracted from itself
