Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575344, here are decompositions:

7 + 31575337 = 31575344
43 + 31575301 = 31575344
103 + 31575241 = 31575344
127 + 31575217 = 31575344
181 + 31575163 = 31575344
193 + 31575151 = 31575344
271 + 31575073 = 31575344
433 + 31574911 = 31575344

Showing the first eight; more decompositions exist.
