Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513930, here are decompositions:

17 + 33513913 = 33513930
19 + 33513911 = 33513930
29 + 33513901 = 33513930
41 + 33513889 = 33513930
53 + 33513877 = 33513930
67 + 33513863 = 33513930
71 + 33513859 = 33513930
89 + 33513841 = 33513930

Showing the first eight; more decompositions exist.
