Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33601428, here are decompositions:

19 + 33601409 = 33601428
71 + 33601357 = 33601428
109 + 33601319 = 33601428
151 + 33601277 = 33601428
167 + 33601261 = 33601428
227 + 33601201 = 33601428
229 + 33601199 = 33601428
241 + 33601187 = 33601428

Showing the first eight; more decompositions exist.
