Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513210, here are decompositions:

7 + 33513203 = 33513210
13 + 33513197 = 33513210
23 + 33513187 = 33513210
43 + 33513167 = 33513210
47 + 33513163 = 33513210
83 + 33513127 = 33513210
103 + 33513107 = 33513210
109 + 33513101 = 33513210

Showing the first eight; more decompositions exist.
