Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507880, here are decompositions:

59 + 33507821 = 33507880
71 + 33507809 = 33507880
83 + 33507797 = 33507880
101 + 33507779 = 33507880
137 + 33507743 = 33507880
191 + 33507689 = 33507880
233 + 33507647 = 33507880
239 + 33507641 = 33507880

Showing the first eight; more decompositions exist.
