Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597206, here are decompositions:

7 + 31597199 = 31597206
29 + 31597177 = 31597206
79 + 31597127 = 31597206
107 + 31597099 = 31597206
163 + 31597043 = 31597206
229 + 31596977 = 31597206
257 + 31596949 = 31597206
283 + 31596923 = 31597206

Showing the first eight; more decompositions exist.
