Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491940, here are decompositions:

11 + 33491929 = 33491940
23 + 33491917 = 33491940
103 + 33491837 = 33491940
107 + 33491833 = 33491940
109 + 33491831 = 33491940
113 + 33491827 = 33491940
137 + 33491803 = 33491940
173 + 33491767 = 33491940

Showing the first eight; more decompositions exist.
