Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550778, here are decompositions:

211 + 33550567 = 33550778
277 + 33550501 = 33550778
337 + 33550441 = 33550778
397 + 33550381 = 33550778
577 + 33550201 = 33550778
661 + 33550117 = 33550778
727 + 33550051 = 33550778
757 + 33550021 = 33550778

Showing the first eight; more decompositions exist.
