Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520880, here are decompositions:

37 + 33520843 = 33520880
67 + 33520813 = 33520880
79 + 33520801 = 33520880
97 + 33520783 = 33520880
103 + 33520777 = 33520880
193 + 33520687 = 33520880
199 + 33520681 = 33520880
277 + 33520603 = 33520880

Showing the first eight; more decompositions exist.
