Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558372, here are decompositions:

31 + 33558341 = 33558372
79 + 33558293 = 33558372
101 + 33558271 = 33558372
103 + 33558269 = 33558372
109 + 33558263 = 33558372
179 + 33558193 = 33558372
193 + 33558179 = 33558372
271 + 33558101 = 33558372

Showing the first eight; more decompositions exist.
