Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520668, here are decompositions:

19 + 33520649 = 33520668
47 + 33520621 = 33520668
107 + 33520561 = 33520668
179 + 33520489 = 33520668
191 + 33520477 = 33520668
197 + 33520471 = 33520668
199 + 33520469 = 33520668
229 + 33520439 = 33520668

Showing the first eight; more decompositions exist.
