Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501972, here are decompositions:

19 + 33501953 = 33501972
79 + 33501893 = 33501972
83 + 33501889 = 33501972
131 + 33501841 = 33501972
173 + 33501799 = 33501972
181 + 33501791 = 33501972
193 + 33501779 = 33501972
239 + 33501733 = 33501972

Showing the first eight; more decompositions exist.
