Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538920, here are decompositions:

7 + 33538913 = 33538920
13 + 33538907 = 33538920
29 + 33538891 = 33538920
47 + 33538873 = 33538920
53 + 33538867 = 33538920
61 + 33538859 = 33538920
97 + 33538823 = 33538920
137 + 33538783 = 33538920

Showing the first eight; more decompositions exist.
