Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597002, here are decompositions:

5 + 31596997 = 31597002
11 + 31596991 = 31597002
53 + 31596949 = 31597002
79 + 31596923 = 31597002
89 + 31596913 = 31597002
103 + 31596899 = 31597002
113 + 31596889 = 31597002
163 + 31596839 = 31597002

Showing the first eight; more decompositions exist.
