Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597256, here are decompositions:

3 + 31597253 = 31597256
13 + 31597243 = 31597256
43 + 31597213 = 31597256
79 + 31597177 = 31597256
127 + 31597129 = 31597256
157 + 31597099 = 31597256
307 + 31596949 = 31597256
349 + 31596907 = 31597256

Showing the first eight; more decompositions exist.
