Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597008, here are decompositions:

5 + 31597003 = 31597008
11 + 31596997 = 31597008
17 + 31596991 = 31597008
31 + 31596977 = 31597008
59 + 31596949 = 31597008
101 + 31596907 = 31597008
109 + 31596899 = 31597008
127 + 31596881 = 31597008

Showing the first eight; more decompositions exist.
