Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597118, here are decompositions:

19 + 31597099 = 31597118
37 + 31597081 = 31597118
67 + 31597051 = 31597118
127 + 31596991 = 31597118
211 + 31596907 = 31597118
229 + 31596889 = 31597118
271 + 31596847 = 31597118
349 + 31596769 = 31597118

Showing the first eight; more decompositions exist.
