Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471864, here are decompositions:

7 + 33471857 = 33471864
11 + 33471853 = 33471864
53 + 33471811 = 33471864
61 + 33471803 = 33471864
131 + 33471733 = 33471864
157 + 33471707 = 33471864
197 + 33471667 = 33471864
271 + 33471593 = 33471864

Showing the first eight; more decompositions exist.
