Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478280, here are decompositions:

7 + 33478273 = 33478280
79 + 33478201 = 33478280
97 + 33478183 = 33478280
103 + 33478177 = 33478280
127 + 33478153 = 33478280
271 + 33478009 = 33478280
349 + 33477931 = 33478280
397 + 33477883 = 33478280

Showing the first eight; more decompositions exist.
