Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553986, here are decompositions:

17 + 33553969 = 33553986
19 + 33553967 = 33553986
107 + 33553879 = 33553986
149 + 33553837 = 33553986
199 + 33553787 = 33553986
227 + 33553759 = 33553986
239 + 33553747 = 33553986
293 + 33553693 = 33553986

Showing the first eight; more decompositions exist.
