Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471940, here are decompositions:

23 + 33471917 = 33471940
41 + 33471899 = 33471940
71 + 33471869 = 33471940
83 + 33471857 = 33471940
137 + 33471803 = 33471940
167 + 33471773 = 33471940
233 + 33471707 = 33471940
251 + 33471689 = 33471940

Showing the first eight; more decompositions exist.
