Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597306, here are decompositions:

23 + 31597283 = 31597306
53 + 31597253 = 31597306
107 + 31597199 = 31597306
179 + 31597127 = 31597306
263 + 31597043 = 31597306
383 + 31596923 = 31597306
449 + 31596857 = 31597306
467 + 31596839 = 31597306

Showing the first eight; more decompositions exist.
