Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597884, here are decompositions:

5 + 31597879 = 31597884
7 + 31597877 = 31597884
11 + 31597873 = 31597884
41 + 31597843 = 31597884
61 + 31597823 = 31597884
83 + 31597801 = 31597884
107 + 31597777 = 31597884
163 + 31597721 = 31597884

Showing the first eight; more decompositions exist.
