Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471918, here are decompositions:

19 + 33471899 = 33471918
61 + 33471857 = 33471918
107 + 33471811 = 33471918
149 + 33471769 = 33471918
197 + 33471721 = 33471918
199 + 33471719 = 33471918
211 + 33471707 = 33471918
229 + 33471689 = 33471918

Showing the first eight; more decompositions exist.
