Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598146, here are decompositions:

3 + 31598143 = 31598146
5 + 31598141 = 31598146
89 + 31598057 = 31598146
113 + 31598033 = 31598146
137 + 31598009 = 31598146
149 + 31597997 = 31598146
233 + 31597913 = 31598146
269 + 31597877 = 31598146

Showing the first eight; more decompositions exist.
