Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597296, here are decompositions:

13 + 31597283 = 31597296
43 + 31597253 = 31597296
53 + 31597243 = 31597296
83 + 31597213 = 31597296
97 + 31597199 = 31597296
167 + 31597129 = 31597296
197 + 31597099 = 31597296
293 + 31597003 = 31597296

Showing the first eight; more decompositions exist.
