Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471972, here are decompositions:

19 + 33471953 = 33471972
73 + 33471899 = 33471972
103 + 33471869 = 33471972
173 + 33471799 = 33471972
199 + 33471773 = 33471972
239 + 33471733 = 33471972
251 + 33471721 = 33471972
263 + 33471709 = 33471972

Showing the first eight; more decompositions exist.
