Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557538, here are decompositions:

17 + 33557521 = 33557538
29 + 33557509 = 33557538
67 + 33557471 = 33557538
71 + 33557467 = 33557538
109 + 33557429 = 33557538
127 + 33557411 = 33557538
139 + 33557399 = 33557538
151 + 33557387 = 33557538

Showing the first eight; more decompositions exist.
