Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456304, here are decompositions:

13 + 31456291 = 31456304
67 + 31456237 = 31456304
181 + 31456123 = 31456304
211 + 31456093 = 31456304
283 + 31456021 = 31456304
463 + 31455841 = 31456304
577 + 31455727 = 31456304
601 + 31455703 = 31456304

Showing the first eight; more decompositions exist.
