Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33529428, here are decompositions:

7 + 33529421 = 33529428
19 + 33529409 = 33529428
41 + 33529387 = 33529428
59 + 33529369 = 33529428
131 + 33529297 = 33529428
137 + 33529291 = 33529428
151 + 33529277 = 33529428
157 + 33529271 = 33529428

Showing the first eight; more decompositions exist.
