Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598256, here are decompositions:

17 + 31598239 = 31598256
29 + 31598227 = 31598256
43 + 31598213 = 31598256
113 + 31598143 = 31598256
199 + 31598057 = 31598256
223 + 31598033 = 31598256
227 + 31598029 = 31598256
229 + 31598027 = 31598256

Showing the first eight; more decompositions exist.
