Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471820, here are decompositions:

17 + 33471803 = 33471820
47 + 33471773 = 33471820
101 + 33471719 = 33471820
113 + 33471707 = 33471820
131 + 33471689 = 33471820
191 + 33471629 = 33471820
227 + 33471593 = 33471820
383 + 33471437 = 33471820

Showing the first eight; more decompositions exist.
