Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543870, here are decompositions:

13 + 33543857 = 33543870
29 + 33543841 = 33543870
67 + 33543803 = 33543870
79 + 33543791 = 33543870
97 + 33543773 = 33543870
109 + 33543761 = 33543870
181 + 33543689 = 33543870
197 + 33543673 = 33543870

Showing the first eight; more decompositions exist.
