Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485920, here are decompositions:

11 + 33485909 = 33485920
29 + 33485891 = 33485920
47 + 33485873 = 33485920
53 + 33485867 = 33485920
89 + 33485831 = 33485920
101 + 33485819 = 33485920
131 + 33485789 = 33485920
179 + 33485741 = 33485920

Showing the first eight; more decompositions exist.
