Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597026, here are decompositions:

23 + 31597003 = 31597026
29 + 31596997 = 31597026
103 + 31596923 = 31597026
113 + 31596913 = 31597026
127 + 31596899 = 31597026
137 + 31596889 = 31597026
179 + 31596847 = 31597026
229 + 31596797 = 31597026

Showing the first eight; more decompositions exist.
