Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482304, here are decompositions:

11 + 31482293 = 31482304
23 + 31482281 = 31482304
47 + 31482257 = 31482304
131 + 31482173 = 31482304
137 + 31482167 = 31482304
257 + 31482047 = 31482304
263 + 31482041 = 31482304
353 + 31481951 = 31482304

Showing the first eight; more decompositions exist.
