Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471520, here are decompositions:

23 + 33471497 = 33471520
29 + 33471491 = 33471520
41 + 33471479 = 33471520
83 + 33471437 = 33471520
167 + 33471353 = 33471520
197 + 33471323 = 33471520
233 + 33471287 = 33471520
347 + 33471173 = 33471520

Showing the first eight; more decompositions exist.
