Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478400, here are decompositions:

13 + 33478387 = 33478400
127 + 33478273 = 33478400
199 + 33478201 = 33478400
211 + 33478189 = 33478400
223 + 33478177 = 33478400
337 + 33478063 = 33478400
607 + 33477793 = 33478400
751 + 33477649 = 33478400

Showing the first eight; more decompositions exist.
