Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520940, here are decompositions:

97 + 33520843 = 33520940
127 + 33520813 = 33520940
139 + 33520801 = 33520940
157 + 33520783 = 33520940
163 + 33520777 = 33520940
181 + 33520759 = 33520940
337 + 33520603 = 33520940
379 + 33520561 = 33520940

Showing the first eight; more decompositions exist.
