Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597124, here are decompositions:

3 + 31597121 = 31597124
43 + 31597081 = 31597124
73 + 31597051 = 31597124
127 + 31596997 = 31597124
211 + 31596913 = 31597124
241 + 31596883 = 31597124
277 + 31596847 = 31597124
331 + 31596793 = 31597124

Showing the first eight; more decompositions exist.
