Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538384, here are decompositions:

17 + 33538367 = 33538384
41 + 33538343 = 33538384
71 + 33538313 = 33538384
137 + 33538247 = 33538384
167 + 33538217 = 33538384
251 + 33538133 = 33538384
281 + 33538103 = 33538384
293 + 33538091 = 33538384

Showing the first eight; more decompositions exist.
