Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511428, here are decompositions:

19 + 33511409 = 33511428
29 + 33511399 = 33511428
31 + 33511397 = 33511428
61 + 33511367 = 33511428
89 + 33511339 = 33511428
107 + 33511321 = 33511428
131 + 33511297 = 33511428
151 + 33511277 = 33511428

Showing the first eight; more decompositions exist.
