Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557760, here are decompositions:

7 + 33557753 = 33557760
11 + 33557749 = 33557760
23 + 33557737 = 33557760
29 + 33557731 = 33557760
31 + 33557729 = 33557760
53 + 33557707 = 33557760
59 + 33557701 = 33557760
79 + 33557681 = 33557760

Showing the first eight; more decompositions exist.
