Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520240, here are decompositions:

59 + 33520181 = 33520240
71 + 33520169 = 33520240
113 + 33520127 = 33520240
137 + 33520103 = 33520240
179 + 33520061 = 33520240
197 + 33520043 = 33520240
227 + 33520013 = 33520240
311 + 33519929 = 33520240

Showing the first eight; more decompositions exist.
