Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491930, here are decompositions:

13 + 33491917 = 33491930
97 + 33491833 = 33491930
103 + 33491827 = 33491930
127 + 33491803 = 33491930
151 + 33491779 = 33491930
163 + 33491767 = 33491930
211 + 33491719 = 33491930
331 + 33491599 = 33491930

Showing the first eight; more decompositions exist.
