Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575846, here are decompositions:

7 + 31575839 = 31575846
13 + 31575833 = 31575846
17 + 31575829 = 31575846
23 + 31575823 = 31575846
47 + 31575799 = 31575846
53 + 31575793 = 31575846
79 + 31575767 = 31575846
103 + 31575743 = 31575846

Showing the first eight; more decompositions exist.
