Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557894, here are decompositions:

3 + 33557891 = 33557894
67 + 33557827 = 33557894
127 + 33557767 = 33557894
157 + 33557737 = 33557894
163 + 33557731 = 33557894
193 + 33557701 = 33557894
211 + 33557683 = 33557894
277 + 33557617 = 33557894

Showing the first eight; more decompositions exist.
