Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478020, here are decompositions:

7 + 33478013 = 33478020
11 + 33478009 = 33478020
19 + 33478001 = 33478020
89 + 33477931 = 33478020
137 + 33477883 = 33478020
139 + 33477881 = 33478020
227 + 33477793 = 33478020
307 + 33477713 = 33478020

Showing the first eight; more decompositions exist.
