Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520578, here are decompositions:

17 + 33520561 = 33520578
89 + 33520489 = 33520578
101 + 33520477 = 33520578
107 + 33520471 = 33520578
109 + 33520469 = 33520578
139 + 33520439 = 33520578
149 + 33520429 = 33520578
181 + 33520397 = 33520578

Showing the first eight; more decompositions exist.
