Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557838, here are decompositions:

11 + 33557827 = 33557838
29 + 33557809 = 33557838
31 + 33557807 = 33557838
71 + 33557767 = 33557838
89 + 33557749 = 33557838
101 + 33557737 = 33557838
107 + 33557731 = 33557838
109 + 33557729 = 33557838

Showing the first eight; more decompositions exist.
