Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520572, here are decompositions:

11 + 33520561 = 33520572
83 + 33520489 = 33520572
101 + 33520471 = 33520572
103 + 33520469 = 33520572
199 + 33520373 = 33520572
251 + 33520321 = 33520572
269 + 33520303 = 33520572
331 + 33520241 = 33520572

Showing the first eight; more decompositions exist.
