Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485928, here are decompositions:

19 + 33485909 = 33485928
37 + 33485891 = 33485928
41 + 33485887 = 33485928
61 + 33485867 = 33485928
89 + 33485839 = 33485928
97 + 33485831 = 33485928
107 + 33485821 = 33485928
109 + 33485819 = 33485928

Showing the first eight; more decompositions exist.
