$\large25^2=15^2+20^2=7^2+24^2$

Below is a list of the first few numbers $$c$$ where $$c^2$$ can be written as the sum of two positive square numbers in at least two different ways:

$$25$$, $$50$$, $$65$$, $$85$$, $$100$$, $$125$$, $$130$$...

All of the numbers mentioned are divisible by 5. Unfortunately, this property doesn't hold for all numbers in this list. What is the first number $$c$$ in this list that isn't divisible by 5?
