Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505830, here are decompositions:

31 + 33505799 = 33505830
41 + 33505789 = 33505830
53 + 33505777 = 33505830
79 + 33505751 = 33505830
107 + 33505723 = 33505830
167 + 33505663 = 33505830
199 + 33505631 = 33505830
229 + 33505601 = 33505830

Showing the first eight; more decompositions exist.
