Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557820, here are decompositions:

11 + 33557809 = 33557820
13 + 33557807 = 33557820
31 + 33557789 = 33557820
53 + 33557767 = 33557820
67 + 33557753 = 33557820
71 + 33557749 = 33557820
83 + 33557737 = 33557820
89 + 33557731 = 33557820

Showing the first eight; more decompositions exist.
