Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575922, here are decompositions:

5 + 31575917 = 31575922
23 + 31575899 = 31575922
29 + 31575893 = 31575922
41 + 31575881 = 31575922
83 + 31575839 = 31575922
89 + 31575833 = 31575922
179 + 31575743 = 31575922
251 + 31575671 = 31575922

Showing the first eight; more decompositions exist.
