Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550978, here are decompositions:

11 + 33550967 = 33550978
29 + 33550949 = 33550978
47 + 33550931 = 33550978
107 + 33550871 = 33550978
179 + 33550799 = 33550978
191 + 33550787 = 33550978
317 + 33550661 = 33550978
347 + 33550631 = 33550978

Showing the first eight; more decompositions exist.
