Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598304, here are decompositions:

5 + 31598299 = 31598304
37 + 31598267 = 31598304
43 + 31598261 = 31598304
103 + 31598201 = 31598304
113 + 31598191 = 31598304
163 + 31598141 = 31598304
167 + 31598137 = 31598304
271 + 31598033 = 31598304

Showing the first eight; more decompositions exist.
