Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520478, here are decompositions:

7 + 33520471 = 33520478
109 + 33520369 = 33520478
157 + 33520321 = 33520478
331 + 33520147 = 33520478
349 + 33520129 = 33520478
499 + 33519979 = 33520478
571 + 33519907 = 33520478
601 + 33519877 = 33520478

Showing the first eight; more decompositions exist.
