Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575852, here are decompositions:

13 + 31575839 = 31575852
19 + 31575833 = 31575852
23 + 31575829 = 31575852
29 + 31575823 = 31575852
53 + 31575799 = 31575852
59 + 31575793 = 31575852
83 + 31575769 = 31575852
109 + 31575743 = 31575852

Showing the first eight; more decompositions exist.
