Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575896, here are decompositions:

3 + 31575893 = 31575896
19 + 31575877 = 31575896
67 + 31575829 = 31575896
73 + 31575823 = 31575896
97 + 31575799 = 31575896
103 + 31575793 = 31575896
127 + 31575769 = 31575896
199 + 31575697 = 31575896

Showing the first eight; more decompositions exist.
