Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513428, here are decompositions:

7 + 33513421 = 33513428
61 + 33513367 = 33513428
181 + 33513247 = 33513428
241 + 33513187 = 33513428
331 + 33513097 = 33513428
499 + 33512929 = 33513428
547 + 33512881 = 33513428
757 + 33512671 = 33513428

Showing the first eight; more decompositions exist.
