Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550868, here are decompositions:

19 + 33550849 = 33550868
37 + 33550831 = 33550868
139 + 33550729 = 33550868
181 + 33550687 = 33550868
277 + 33550591 = 33550868
367 + 33550501 = 33550868
487 + 33550381 = 33550868
541 + 33550327 = 33550868

Showing the first eight; more decompositions exist.
