Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513918, here are decompositions:

5 + 33513913 = 33513918
7 + 33513911 = 33513918
17 + 33513901 = 33513918
29 + 33513889 = 33513918
37 + 33513881 = 33513918
41 + 33513877 = 33513918
59 + 33513859 = 33513918
79 + 33513839 = 33513918

Showing the first eight; more decompositions exist.
