Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505818, here are decompositions:

19 + 33505799 = 33505818
29 + 33505789 = 33505818
37 + 33505781 = 33505818
41 + 33505777 = 33505818
67 + 33505751 = 33505818
197 + 33505621 = 33505818
239 + 33505579 = 33505818
251 + 33505567 = 33505818

Showing the first eight; more decompositions exist.
