Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598960, here are decompositions:

7 + 31598953 = 31598960
13 + 31598947 = 31598960
37 + 31598923 = 31598960
73 + 31598887 = 31598960
97 + 31598863 = 31598960
103 + 31598857 = 31598960
181 + 31598779 = 31598960
277 + 31598683 = 31598960

Showing the first eight; more decompositions exist.
