Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478328, here are decompositions:

97 + 33478231 = 33478328
127 + 33478201 = 33478328
139 + 33478189 = 33478328
151 + 33478177 = 33478328
397 + 33477931 = 33478328
769 + 33477559 = 33478328
811 + 33477517 = 33478328
937 + 33477391 = 33478328

Showing the first eight; more decompositions exist.
