Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485970, here are decompositions:

13 + 33485957 = 33485970
29 + 33485941 = 33485970
31 + 33485939 = 33485970
61 + 33485909 = 33485970
79 + 33485891 = 33485970
83 + 33485887 = 33485970
97 + 33485873 = 33485970
103 + 33485867 = 33485970

Showing the first eight; more decompositions exist.
