Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557578, here are decompositions:

11 + 33557567 = 33557578
17 + 33557561 = 33557578
107 + 33557471 = 33557578
149 + 33557429 = 33557578
167 + 33557411 = 33557578
179 + 33557399 = 33557578
191 + 33557387 = 33557578
239 + 33557339 = 33557578

Showing the first eight; more decompositions exist.
