Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507660, here are decompositions:

13 + 33507647 = 33507660
19 + 33507641 = 33507660
29 + 33507631 = 33507660
37 + 33507623 = 33507660
59 + 33507601 = 33507660
61 + 33507599 = 33507660
83 + 33507577 = 33507660
97 + 33507563 = 33507660

Showing the first eight; more decompositions exist.
