Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538528, here are decompositions:

5 + 33538523 = 33538528
11 + 33538517 = 33538528
17 + 33538511 = 33538528
29 + 33538499 = 33538528
47 + 33538481 = 33538528
59 + 33538469 = 33538528
71 + 33538457 = 33538528
269 + 33538259 = 33538528

Showing the first eight; more decompositions exist.
