Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491970, here are decompositions:

11 + 33491959 = 33491970
41 + 33491929 = 33491970
53 + 33491917 = 33491970
137 + 33491833 = 33491970
139 + 33491831 = 33491970
167 + 33491803 = 33491970
191 + 33491779 = 33491970
223 + 33491747 = 33491970

Showing the first eight; more decompositions exist.
