Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513948, here are decompositions:

5 + 33513943 = 33513948
37 + 33513911 = 33513948
47 + 33513901 = 33513948
59 + 33513889 = 33513948
67 + 33513881 = 33513948
71 + 33513877 = 33513948
89 + 33513859 = 33513948
107 + 33513841 = 33513948

Showing the first eight; more decompositions exist.
