Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598230, here are decompositions:

3 + 31598227 = 31598230
17 + 31598213 = 31598230
29 + 31598201 = 31598230
89 + 31598141 = 31598230
173 + 31598057 = 31598230
197 + 31598033 = 31598230
233 + 31597997 = 31598230
269 + 31597961 = 31598230

Showing the first eight; more decompositions exist.
