Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33471928, here are decompositions:

11 + 33471917 = 33471928
29 + 33471899 = 33471928
59 + 33471869 = 33471928
71 + 33471857 = 33471928
239 + 33471689 = 33471928
251 + 33471677 = 33471928
431 + 33471497 = 33471928
449 + 33471479 = 33471928

Showing the first eight; more decompositions exist.
