Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598916, here are decompositions:

5 + 31598911 = 31598916
7 + 31598909 = 31598916
29 + 31598887 = 31598916
43 + 31598873 = 31598916
53 + 31598863 = 31598916
59 + 31598857 = 31598916
127 + 31598789 = 31598916
137 + 31598779 = 31598916

Showing the first eight; more decompositions exist.
