Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472020, here are decompositions:

11 + 33472009 = 33472020
13 + 33472007 = 33472020
31 + 33471989 = 33472020
41 + 33471979 = 33472020
47 + 33471973 = 33472020
67 + 33471953 = 33472020
73 + 33471947 = 33472020
103 + 33471917 = 33472020

Showing the first eight; more decompositions exist.
