Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557568, here are decompositions:

7 + 33557561 = 33557568
47 + 33557521 = 33557568
59 + 33557509 = 33557568
97 + 33557471 = 33557568
101 + 33557467 = 33557568
139 + 33557429 = 33557568
151 + 33557417 = 33557568
157 + 33557411 = 33557568

Showing the first eight; more decompositions exist.
