Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557632, here are decompositions:

5 + 33557627 = 33557632
29 + 33557603 = 33557632
71 + 33557561 = 33557632
89 + 33557543 = 33557632
179 + 33557453 = 33557632
233 + 33557399 = 33557632
293 + 33557339 = 33557632
569 + 33557063 = 33557632

Showing the first eight; more decompositions exist.
