Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509538, here are decompositions:

11 + 33509527 = 33509538
37 + 33509501 = 33509538
109 + 33509429 = 33509538
137 + 33509401 = 33509538
149 + 33509389 = 33509538
211 + 33509327 = 33509538
269 + 33509269 = 33509538
281 + 33509257 = 33509538

Showing the first eight; more decompositions exist.
