Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520140, here are decompositions:

11 + 33520129 = 33520140
13 + 33520127 = 33520140
37 + 33520103 = 33520140
53 + 33520087 = 33520140
79 + 33520061 = 33520140
89 + 33520051 = 33520140
97 + 33520043 = 33520140
109 + 33520031 = 33520140

Showing the first eight; more decompositions exist.
