Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533388, here are decompositions:

19 + 33533369 = 33533388
47 + 33533341 = 33533388
59 + 33533329 = 33533388
67 + 33533321 = 33533388
71 + 33533317 = 33533388
107 + 33533281 = 33533388
127 + 33533261 = 33533388
131 + 33533257 = 33533388

Showing the first eight; more decompositions exist.
