Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557918, here are decompositions:

7 + 33557911 = 33557918
19 + 33557899 = 33557918
109 + 33557809 = 33557918
151 + 33557767 = 33557918
181 + 33557737 = 33557918
211 + 33557707 = 33557918
397 + 33557521 = 33557918
409 + 33557509 = 33557918

Showing the first eight; more decompositions exist.
