Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507768, here are decompositions:

5 + 33507763 = 33507768
17 + 33507751 = 33507768
31 + 33507737 = 33507768
79 + 33507689 = 33507768
89 + 33507679 = 33507768
97 + 33507671 = 33507768
127 + 33507641 = 33507768
137 + 33507631 = 33507768

Showing the first eight; more decompositions exist.
