Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499728, here are decompositions:

7 + 33499721 = 33499728
37 + 33499691 = 33499728
79 + 33499649 = 33499728
107 + 33499621 = 33499728
109 + 33499619 = 33499728
127 + 33499601 = 33499728
137 + 33499591 = 33499728
151 + 33499577 = 33499728

Showing the first eight; more decompositions exist.
