Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558420, here are decompositions:

13 + 33558407 = 33558420
47 + 33558373 = 33558420
79 + 33558341 = 33558420
127 + 33558293 = 33558420
139 + 33558281 = 33558420
149 + 33558271 = 33558420
151 + 33558269 = 33558420
157 + 33558263 = 33558420

Showing the first eight; more decompositions exist.
