Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478220, here are decompositions:

19 + 33478201 = 33478220
31 + 33478189 = 33478220
37 + 33478183 = 33478220
43 + 33478177 = 33478220
67 + 33478153 = 33478220
109 + 33478111 = 33478220
157 + 33478063 = 33478220
211 + 33478009 = 33478220

Showing the first eight; more decompositions exist.
