Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528388, here are decompositions:

11 + 33528377 = 33528388
167 + 33528221 = 33528388
239 + 33528149 = 33528388
251 + 33528137 = 33528388
347 + 33528041 = 33528388
389 + 33527999 = 33528388
419 + 33527969 = 33528388
479 + 33527909 = 33528388

Showing the first eight; more decompositions exist.
