Problem 60791. Sum of Even Fibonacci Numbers

Description:
The Fibonacci sequence is defined as follows:F(1)=1,F(2)=1,F(n)=F(n−1)+F(n−2) for n>2
Write a function that computes the sum of all even Fibonacci numbers that do not exceed a given number NNN.
Example:
For N=10, the Fibonacci sequence up to 10 is:
1,1,2,3,5,8
The even numbers are 2 and 8, and their sum is 10.
