Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507712, here are decompositions:

23 + 33507689 = 33507712
41 + 33507671 = 33507712
71 + 33507641 = 33507712
89 + 33507623 = 33507712
101 + 33507611 = 33507712
113 + 33507599 = 33507712
149 + 33507563 = 33507712
269 + 33507443 = 33507712

Showing the first eight; more decompositions exist.
