"Pairs of integers"
The input file consists of several test cases.
Each test case contains single integer N (10 ≤ N ≤ 109), as decribed above
The output consists of several blocks, one for each test case.
On the first line of a block write the total number of different pairs of integers that satisfy the problem statement. On the following lines write all those pairs. Write one pair on a line in ascending order of the first integer in the pair. Each pair must be written in the following format:
X + Y = N
Here X, Y, and N, must be replaced with the corresponding integer numbers. There should be exactly one space on both sides of '+' and '=' characters.
5 251 + 51 = 302 275 + 27 = 302 276 + 26 = 302 281 + 21 = 302 301 + 01 = 302
