Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538188, here are decompositions:

29 + 33538159 = 33538188
59 + 33538129 = 33538188
97 + 33538091 = 33538188
107 + 33538081 = 33538188
137 + 33538051 = 33538188
139 + 33538049 = 33538188
179 + 33538009 = 33538188
227 + 33537961 = 33538188

Showing the first eight; more decompositions exist.
