Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471930, here are decompositions:

13 + 33471917 = 33471930
31 + 33471899 = 33471930
61 + 33471869 = 33471930
73 + 33471857 = 33471930
127 + 33471803 = 33471930
131 + 33471799 = 33471930
157 + 33471773 = 33471930
197 + 33471733 = 33471930

Showing the first eight; more decompositions exist.
