Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513938, here are decompositions:

37 + 33513901 = 33513938
61 + 33513877 = 33513938
79 + 33513859 = 33513938
97 + 33513841 = 33513938
127 + 33513811 = 33513938
277 + 33513661 = 33513938
307 + 33513631 = 33513938
379 + 33513559 = 33513938

Showing the first eight; more decompositions exist.
