Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543972, here are decompositions:

43 + 33543929 = 33543972
71 + 33543901 = 33543972
73 + 33543899 = 33543972
131 + 33543841 = 33543972
181 + 33543791 = 33543972
199 + 33543773 = 33543972
211 + 33543761 = 33543972
263 + 33543709 = 33543972

Showing the first eight; more decompositions exist.
