Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611388, here are decompositions:

29 + 33611359 = 33611388
37 + 33611351 = 33611388
47 + 33611341 = 33611388
61 + 33611327 = 33611388
67 + 33611321 = 33611388
79 + 33611309 = 33611388
197 + 33611191 = 33611388
211 + 33611177 = 33611388

Showing the first eight; more decompositions exist.
