Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597310, here are decompositions:

67 + 31597243 = 31597310
79 + 31597231 = 31597310
97 + 31597213 = 31597310
181 + 31597129 = 31597310
211 + 31597099 = 31597310
229 + 31597081 = 31597310
307 + 31597003 = 31597310
313 + 31596997 = 31597310

Showing the first eight; more decompositions exist.
