Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558378, here are decompositions:

5 + 33558373 = 33558378
37 + 33558341 = 33558378
97 + 33558281 = 33558378
107 + 33558271 = 33558378
109 + 33558269 = 33558378
131 + 33558247 = 33558378
167 + 33558211 = 33558378
199 + 33558179 = 33558378

Showing the first eight; more decompositions exist.
