Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513912, here are decompositions:

11 + 33513901 = 33513912
23 + 33513889 = 33513912
31 + 33513881 = 33513912
53 + 33513859 = 33513912
71 + 33513841 = 33513912
73 + 33513839 = 33513912
101 + 33513811 = 33513912
151 + 33513761 = 33513912

Showing the first eight; more decompositions exist.
