Except when it doesn't:
450000 11028 455000 7526 460000 5840
which, by your reasoning, would show that Goldbach's conjecture is false.

The point isn't to show a general trend, but to show that it's *always* the case. The general trend is what led Goldbach to make this conjecture, and the reason that most mathematicians think that the conjecture is probably true.
"Probably true" is easy; "proved" is hard.
