Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499128, here are decompositions:

7 + 33499121 = 33499128
11 + 33499117 = 33499128
71 + 33499057 = 33499128
137 + 33498991 = 33499128
149 + 33498979 = 33499128
197 + 33498931 = 33499128
227 + 33498901 = 33499128
241 + 33498887 = 33499128

Showing the first eight; more decompositions exist.
