Challenge ::: The Wonderbook.

Question

You have a Wonderbook which has only two pages. If you write two natural numbers in these two pages and reopen the book, it erases them and returns you their product and sum.
For example : If you write 4 and 5, the next time you open the book, the numbers become 20 and 9. Again you close the book and reopen to find they have changed to 180 and 29.
4,5=>9,20=>180,29
1,2=>2,3=>6,5

Make a program to find how many ways are there to appear a inputted number into the book without writing it.
