Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597010, here are decompositions:

7 + 31597003 = 31597010
13 + 31596997 = 31597010
19 + 31596991 = 31597010
61 + 31596949 = 31597010
97 + 31596913 = 31597010
103 + 31596907 = 31597010
127 + 31596883 = 31597010
163 + 31596847 = 31597010

Showing the first eight; more decompositions exist.
