Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557946, here are decompositions:

5 + 33557941 = 33557946
29 + 33557917 = 33557946
47 + 33557899 = 33557946
53 + 33557893 = 33557946
67 + 33557879 = 33557946
109 + 33557837 = 33557946
137 + 33557809 = 33557946
139 + 33557807 = 33557946

Showing the first eight; more decompositions exist.
