Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501728, here are decompositions:

19 + 33501709 = 33501728
31 + 33501697 = 33501728
37 + 33501691 = 33501728
61 + 33501667 = 33501728
79 + 33501649 = 33501728
97 + 33501631 = 33501728
109 + 33501619 = 33501728
157 + 33501571 = 33501728

Showing the first eight; more decompositions exist.
