Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575934, here are decompositions:

11 + 31575923 = 31575934
17 + 31575917 = 31575934
41 + 31575893 = 31575934
53 + 31575881 = 31575934
101 + 31575833 = 31575934
167 + 31575767 = 31575934
191 + 31575743 = 31575934
197 + 31575737 = 31575934

Showing the first eight; more decompositions exist.
