Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538392, here are decompositions:

5 + 33538387 = 33538392
53 + 33538339 = 33538392
71 + 33538321 = 33538392
79 + 33538313 = 33538392
89 + 33538303 = 33538392
233 + 33538159 = 33538392
263 + 33538129 = 33538392
311 + 33538081 = 33538392

Showing the first eight; more decompositions exist.
