Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557940, here are decompositions:

19 + 33557921 = 33557940
23 + 33557917 = 33557940
29 + 33557911 = 33557940
41 + 33557899 = 33557940
47 + 33557893 = 33557940
61 + 33557879 = 33557940
103 + 33557837 = 33557940
113 + 33557827 = 33557940

Showing the first eight; more decompositions exist.
