Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551168, here are decompositions:

61 + 33551107 = 33551168
127 + 33551041 = 33551168
229 + 33550939 = 33551168
337 + 33550831 = 33551168
439 + 33550729 = 33551168
577 + 33550591 = 33551168
601 + 33550567 = 33551168
727 + 33550441 = 33551168

Showing the first eight; more decompositions exist.
