Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471872, here are decompositions:

3 + 33471869 = 33471872
19 + 33471853 = 33471872
61 + 33471811 = 33471872
73 + 33471799 = 33471872
103 + 33471769 = 33471872
139 + 33471733 = 33471872
151 + 33471721 = 33471872
163 + 33471709 = 33471872

Showing the first eight; more decompositions exist.
