Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597086, here are decompositions:

5 + 31597081 = 31597086
43 + 31597043 = 31597086
83 + 31597003 = 31597086
89 + 31596997 = 31597086
109 + 31596977 = 31597086
137 + 31596949 = 31597086
163 + 31596923 = 31597086
173 + 31596913 = 31597086

Showing the first eight; more decompositions exist.
