Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491984, here are decompositions:

3 + 33491981 = 33491984
7 + 33491977 = 33491984
67 + 33491917 = 33491984
151 + 33491833 = 33491984
157 + 33491827 = 33491984
181 + 33491803 = 33491984
223 + 33491761 = 33491984
271 + 33491713 = 33491984

Showing the first eight; more decompositions exist.
