None.
If you add two even numbers, you'll end up with another even number.
No sum of any even numbers can add up to an odd number.
The given numbers of 15 and 35 are not prime numbers but they add up to 50

No sum of any even numbers can add up to an odd number.
There are no four consecutive whole numbers that add up to 35. The sum of two consecutive [whole] numbers is an even number plus an odd number which is an odd number. The sum of two consecutive numbers and the two next consecutive numbers is the sum of two odd numbers which is even, but 35 is odd, so no four consecutive whole numbers cannot add up to 35.

An odd number of odd numbers can not add up to an even number. There fore any 9 (odd) odd numbers can not add up to 50 (even).

They will always add up to another even number.
To find two numbers that add up to 35, we can set up an equation as x + y = 35. There are infinite pairs of numbers that satisfy this equation, such as 20 and 15, 25 and 10, or even fractions like 17.5 and 17.5. The sum of any two numbers that satisfy x + y = 35 will always be 35.
