Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507820, here are decompositions:

11 + 33507809 = 33507820
23 + 33507797 = 33507820
41 + 33507779 = 33507820
83 + 33507737 = 33507820
131 + 33507689 = 33507820
149 + 33507671 = 33507820
173 + 33507647 = 33507820
179 + 33507641 = 33507820

Showing the first eight; more decompositions exist.
