Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506388, here are decompositions:

29 + 33506359 = 33506388
67 + 33506321 = 33506388
79 + 33506309 = 33506388
89 + 33506299 = 33506388
127 + 33506261 = 33506388
137 + 33506251 = 33506388
257 + 33506131 = 33506388
277 + 33506111 = 33506388

Showing the first eight; more decompositions exist.
