Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553856, here are decompositions:

19 + 33553837 = 33553856
97 + 33553759 = 33553856
109 + 33553747 = 33553856
163 + 33553693 = 33553856
199 + 33553657 = 33553856
223 + 33553633 = 33553856
307 + 33553549 = 33553856
337 + 33553519 = 33553856

Showing the first eight; more decompositions exist.
