Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520158, here are decompositions:

11 + 33520147 = 33520158
29 + 33520129 = 33520158
31 + 33520127 = 33520158
71 + 33520087 = 33520158
97 + 33520061 = 33520158
107 + 33520051 = 33520158
127 + 33520031 = 33520158
179 + 33519979 = 33520158

Showing the first eight; more decompositions exist.
