There are infinitely many answers.
Start with integers:
-39, 3
-38, 2
-37, 1
-36, 0
-35, -1
-34, -2
the list can be extended in both directions.
Now, between and two integers, there are infinitely many rational numbers, ad each one has a partner such that their sum will be -36. For example,
-37.2, 1.2
-37.1, 1.1 [37.0 has already been done, as 37]
-36.9, 0.9
-36.8, 0.8
...
-36.1, 0.1 [36.0 has already been done, as 36]
-35.9, -0.1
etc.
And then there are decimals to 2 digits, to 3 digits, ...
And then you can bring in Irrational Numbers
Finally, if you are really adventurous, you could use pairs of complex numbers as well.

36 inches plus what?
27 + 9 = 36
21 + 15 = 36
36 + 12 = 48
