Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597446, here are decompositions:

29 + 31597417 = 31597446
79 + 31597367 = 31597446
109 + 31597337 = 31597446
163 + 31597283 = 31597446
193 + 31597253 = 31597446
233 + 31597213 = 31597446
269 + 31597177 = 31597446
317 + 31597129 = 31597446

Showing the first eight; more decompositions exist.
