Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538288, here are decompositions:

29 + 33538259 = 33538288
41 + 33538247 = 33538288
71 + 33538217 = 33538288
197 + 33538091 = 33538288
239 + 33538049 = 33538288
317 + 33537971 = 33538288
347 + 33537941 = 33538288
389 + 33537899 = 33538288

Showing the first eight; more decompositions exist.
