Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513900, here are decompositions:

11 + 33513889 = 33513900
19 + 33513881 = 33513900
23 + 33513877 = 33513900
37 + 33513863 = 33513900
41 + 33513859 = 33513900
59 + 33513841 = 33513900
61 + 33513839 = 33513900
89 + 33513811 = 33513900

Showing the first eight; more decompositions exist.
