Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538120, here are decompositions:

17 + 33538103 = 33538120
29 + 33538091 = 33538120
71 + 33538049 = 33538120
107 + 33538013 = 33538120
149 + 33537971 = 33538120
179 + 33537941 = 33538120
257 + 33537863 = 33538120
263 + 33537857 = 33538120

Showing the first eight; more decompositions exist.
