Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520000, here are decompositions:

71 + 33519929 = 33520000
251 + 33519749 = 33520000
383 + 33519617 = 33520000
461 + 33519539 = 33520000
659 + 33519341 = 33520000
677 + 33519323 = 33520000
719 + 33519281 = 33520000
911 + 33519089 = 33520000

Showing the first eight; more decompositions exist.
