Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597006, here are decompositions:

3 + 31597003 = 31597006
29 + 31596977 = 31597006
83 + 31596923 = 31597006
107 + 31596899 = 31597006
149 + 31596857 = 31597006
167 + 31596839 = 31597006
257 + 31596749 = 31597006
263 + 31596743 = 31597006

Showing the first eight; more decompositions exist.
