Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525972, here are decompositions:

23 + 33525949 = 33525972
41 + 33525931 = 33525972
71 + 33525901 = 33525972
83 + 33525889 = 33525972
89 + 33525883 = 33525972
101 + 33525871 = 33525972
113 + 33525859 = 33525972
199 + 33525773 = 33525972

Showing the first eight; more decompositions exist.
