Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557428, here are decompositions:

5 + 33557423 = 33557428
11 + 33557417 = 33557428
17 + 33557411 = 33557428
29 + 33557399 = 33557428
41 + 33557387 = 33557428
71 + 33557357 = 33557428
89 + 33557339 = 33557428
101 + 33557327 = 33557428

Showing the first eight; more decompositions exist.
