Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597060, here are decompositions:

17 + 31597043 = 31597060
29 + 31597031 = 31597060
83 + 31596977 = 31597060
137 + 31596923 = 31597060
179 + 31596881 = 31597060
239 + 31596821 = 31597060
263 + 31596797 = 31597060
311 + 31596749 = 31597060

Showing the first eight; more decompositions exist.
