Dear Sanjana,

You have not provided sufficient information or you had copied the question incorrectly. Consider a case in which 'a' and 'b' be 3 and 5 (which are prime no.'s) respectively, and 'x' be 10 (which is >= 4 and also an even no.). Then, 'x is not equal to (a+b) [Since, 8 is not equal to 10].

Kindly, post the question correctly.

Please feel free to post as many doubts on our discussion forum as you can. If you find any question

Anyone who solves this is entitled to $ 1 million from Clay Math Institute, because you would be proving the Goldbach conjecture that has remained unproved for several decades!
