Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507828, here are decompositions:

7 + 33507821 = 33507828
19 + 33507809 = 33507828
31 + 33507797 = 33507828
47 + 33507781 = 33507828
139 + 33507689 = 33507828
149 + 33507679 = 33507828
157 + 33507671 = 33507828
181 + 33507647 = 33507828

Showing the first eight; more decompositions exist.
