Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471880, here are decompositions:

11 + 33471869 = 33471880
23 + 33471857 = 33471880
107 + 33471773 = 33471880
173 + 33471707 = 33471880
191 + 33471689 = 33471880
251 + 33471629 = 33471880
347 + 33471533 = 33471880
383 + 33471497 = 33471880

Showing the first eight; more decompositions exist.
