Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457304, here are decompositions:

7 + 31457297 = 31457304
17 + 31457287 = 31457304
37 + 31457267 = 31457304
101 + 31457203 = 31457304
103 + 31457201 = 31457304
211 + 31457093 = 31457304
223 + 31457081 = 31457304
233 + 31457071 = 31457304

Showing the first eight; more decompositions exist.
