Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520784, here are decompositions:

7 + 33520777 = 33520784
97 + 33520687 = 33520784
103 + 33520681 = 33520784
163 + 33520621 = 33520784
181 + 33520603 = 33520784
223 + 33520561 = 33520784
307 + 33520477 = 33520784
313 + 33520471 = 33520784

Showing the first eight; more decompositions exist.
