HI :)
here is my submission : 22598258
It dosen't use Goldbach's Conjecture .
Do you think this solution is true ? or testcases were weak?

Why 200? Why 1900? As long as these numbers are randomly selected your solution is wrong.
I think this solution is wrong too ...
and i use 200 & 1900 to dont get TLE .
but also this one :22599100 (200 and 40000)didn't get TLE too ...
Well, you've answered your own question!
actually i want a testcase that make my solution wrong ...
but i can not find that
You are assumimg that any even number n < 109 can be decomposed as n = p + q with p, q primes and p < 1900. Similar for odd number n = p + q + t with p, q < 200.
I've tried some random n and the maximum minimum p I could get is 1171, for n = 343553258.
acctualy test 65 has n=1847133842 which 1800<p<1900 and that was maximum p among the tests.
Then I guess the two-prime part is correct. OEIS has only 335070838 with p=1427.
So do you have any idea about 3 prime part?
