Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477388, here are decompositions:

41 + 33477347 = 33477388
71 + 33477317 = 33477388
137 + 33477251 = 33477388
149 + 33477239 = 33477388
227 + 33477161 = 33477388
317 + 33477071 = 33477388
389 + 33476999 = 33477388
617 + 33476771 = 33477388

Showing the first eight; more decompositions exist.
