Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513216, here are decompositions:

13 + 33513203 = 33513216
19 + 33513197 = 33513216
29 + 33513187 = 33513216
53 + 33513163 = 33513216
83 + 33513133 = 33513216
89 + 33513127 = 33513216
109 + 33513107 = 33513216
193 + 33513023 = 33513216

Showing the first eight; more decompositions exist.
