Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507858, here are decompositions:

5 + 33507853 = 33507858
37 + 33507821 = 33507858
61 + 33507797 = 33507858
79 + 33507779 = 33507858
107 + 33507751 = 33507858
179 + 33507679 = 33507858
211 + 33507647 = 33507858
227 + 33507631 = 33507858

Showing the first eight; more decompositions exist.
