Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490180, here are decompositions:

71 + 33490109 = 33490180
83 + 33490097 = 33490180
89 + 33490091 = 33490180
107 + 33490073 = 33490180
137 + 33490043 = 33490180
149 + 33490031 = 33490180
173 + 33490007 = 33490180
233 + 33489947 = 33490180

Showing the first eight; more decompositions exist.
