Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503388, here are decompositions:

19 + 33503369 = 33503388
31 + 33503357 = 33503388
89 + 33503299 = 33503388
101 + 33503287 = 33503388
109 + 33503279 = 33503388
211 + 33503177 = 33503388
227 + 33503161 = 33503388
307 + 33503081 = 33503388

Showing the first eight; more decompositions exist.
