The sum of the squares of certain unusual integers is equal to the concatenation of their individual digits.

For example:

1233 = 12^2+33^2

990100 = 990^2+100^2

Given a number n, write a function that returns true if the number displays this property, and false otherwise. The number of digits will always be even.
