Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575304, here are decompositions:

3 + 31575301 = 31575304
23 + 31575281 = 31575304
71 + 31575233 = 31575304
83 + 31575221 = 31575304
197 + 31575107 = 31575304
263 + 31575041 = 31575304
443 + 31574861 = 31575304
491 + 31574813 = 31575304

Showing the first eight; more decompositions exist.
