Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557888, here are decompositions:

61 + 33557827 = 33557888
79 + 33557809 = 33557888
139 + 33557749 = 33557888
151 + 33557737 = 33557888
157 + 33557731 = 33557888
181 + 33557707 = 33557888
271 + 33557617 = 33557888
367 + 33557521 = 33557888

Showing the first eight; more decompositions exist.
