Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557856, here are decompositions:

19 + 33557837 = 33557856
29 + 33557827 = 33557856
47 + 33557809 = 33557856
67 + 33557789 = 33557856
89 + 33557767 = 33557856
103 + 33557753 = 33557856
107 + 33557749 = 33557856
127 + 33557729 = 33557856

Showing the first eight; more decompositions exist.
