Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558390, here are decompositions:

17 + 33558373 = 33558390
97 + 33558293 = 33558390
109 + 33558281 = 33558390
127 + 33558263 = 33558390
137 + 33558253 = 33558390
179 + 33558211 = 33558390
197 + 33558193 = 33558390
211 + 33558179 = 33558390

Showing the first eight; more decompositions exist.
