Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464704, here are decompositions:

3 + 31464701 = 31464704
127 + 31464577 = 31464704
157 + 31464547 = 31464704
211 + 31464493 = 31464704
223 + 31464481 = 31464704
241 + 31464463 = 31464704
277 + 31464427 = 31464704
283 + 31464421 = 31464704

Showing the first eight; more decompositions exist.
