Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597226, here are decompositions:

13 + 31597213 = 31597226
97 + 31597129 = 31597226
127 + 31597099 = 31597226
223 + 31597003 = 31597226
229 + 31596997 = 31597226
277 + 31596949 = 31597226
313 + 31596913 = 31597226
337 + 31596889 = 31597226

Showing the first eight; more decompositions exist.
