Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575244, here are decompositions:

3 + 31575241 = 31575244
11 + 31575233 = 31575244
23 + 31575221 = 31575244
83 + 31575161 = 31575244
137 + 31575107 = 31575244
263 + 31574981 = 31575244
317 + 31574927 = 31575244
353 + 31574891 = 31575244

Showing the first eight; more decompositions exist.
