Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551540, here are decompositions:

7 + 33551533 = 33551540
13 + 33551527 = 33551540
31 + 33551509 = 33551540
79 + 33551461 = 33551540
163 + 33551377 = 33551540
223 + 33551317 = 33551540
241 + 33551299 = 33551540
283 + 33551257 = 33551540

Showing the first eight; more decompositions exist.
